Arrival instructions

The seminar venue is Hotel Katajanokka. It is an old prison, which has been beautifully renovated into a stylish hotel. The address of the hotel is Merikasarminkatu 1A, Helsinki.

You can get to the hotel by using public transport or a taxi. Here are some instructions on how to get to the venue from the airport or railway station.

By public transport

Helsinki Airport – Central Railway station
You can get easily from Helsinki Airport to the city center by using the Helsinki regional trains I and P going in direction Helsinki. The trains leave every 10 minutes and the trip to the Central Railway Station takes about 30 minutes. The airport railway station is located right beneath the airport terminal and there is a straight escalator connection from the arrival and departure halls down to the railway station.

The HSL (Helsinki regional transport) ticket costs 4,10 € (choose zones ABC) and you can purchase your ticket at one of the ticket machines at the airport railway station. The ticket is valid for any bus, tram or train in the Helsinki region for 80 minutes after purchase.

Central Railway station – Hotel Katajanokka
From the Central Railway Station it is a short walk (max. 5 minutes) to the tram stop called Lasipalatsi (platform 52). Take the tram #4 towards Katajanokka (to hotel 10 min). The hotel’s tram stop is called Vyökatu and it is directly in front of the hotel.

Public transport is very reliable, safe and easy to use in Finland. You can find more information about the timetables and how to buy a ticket here:

By taxi

If you wish, you can take a taxi from the airport to the hotel. Taxi prices vary a lot, but the trip from Helsinki Airport to Hotel Katajanokka costs 50€ on average.

Another possibility is to come by train from the airport to the city center (30 min) and to take a taxi from the Central Railway Station to the venue. The taxi from the railway station to the hotel costs around 20€.

About the excursion

On Thursday afternoon there will be an excursion to Suomenlinna and Lonna islands. We will travel to Suomenlinna by water bus (15 min). The water bus to Suomenlinna leaves at 16:20 from the Market Square (Kauppatori), which is a 10 min walk away from the hotel. In Suomenlinna there will be some coffee and sandwiches as well as a guided walking tour. We recommend wearing good shoes for the trip.

We will leave Suomenlinna with a water bus leaving from the Kings’ Gate pier (Kuninkaanportin laituri) at 18:45. On the ride back, we will get off at a small island called Lonna for dinner. After dinner there is the possibility to go to the sauna and take a refreshing swim in the sea. If you wish to get this Finnish experience, bring your swimming suit with you.

From Lonna, you can get back to the hotel by water bus. The water buses leave once in an hour (20:45 / 21:45 / 22:45 / 23:45) and the last water bus from the island leaves at 00:30.

Background about Suomenlinna and Lonna

Suomenlinna (also known as Sveaborg) is a sea fortress composed of eight islands. It is also one of Helsinki’s districts with about 800 residents.

The fortification work of Suomenlinna began in 1748 by the Swedish crown as protection against Russian expansionism. As Russia invaded Finland in 1809, Suomenlinna became a military base under Russian administration. After Finland was declared an independent nation in 1917, Suomenlinna became a Finnish garrison. The Defence Forces vacated the fortress in the 1970s and nowadays Suomenlinna is in residential use.

Suomenlinna has been a UNESCO World Heritage Site since 1991 and it is one of the most popular tourist attractions in Finland. It is a beautiful place with stunning scenery, fascinating history and many interesting sights. You can find more information about Suomenlinna here:

Lonna is a small island located between Suomenlinna and Helsinki’s Market Square. During the Russian era Lonna was called the negotiation island, because Sweden and Russia negotiated the surrender of the fortress here at the end of the Finnish War in 1808-1809. Lonna was later used as a base for storing and clearing mines.

Since 2014 Lonna has been open to everyone as a haven from the hustle of city life. The island has a public sauna and a popular restaurant as well as a cozy coffee shop & bar.

Hotel reservations

Invited speakers’ accommodation is arranged and covered by organisers. Please contact Brett Maranjian for details.

The other participants (e.g. co-authors of the seminar papers) covering their own expenses are advised to make their own bookings at Hotel Katajanokka via their online service. Please note that the hotel has recently become a part of Strawberry’s portfolio of independent hotels Nordic Hotels & Resorts (instead of Clarion hotels). This may cause some delays in the processing of reservations.

Fun facts about Finland

  • During the conference, the days are almost at their longest in Finland. In Helsinki, the sun won’t set until 22:45 and rises already at 3:55. In northern Finland the sun won’t set at all for 2,5 months and the sun shines all night.
  • Tap water is safe to drink everywhere in Finland. It is among the highest quality in the world and in fact even cleaner than bottled water.
  • Public transport is very safe, reliable and inexpensive in Finland. In Helsinki there are good tram, bus, metro, and train connections everywhere in the city and with a HSL (Helsinki regional transport) ticket you can use any of these vehicles. Please note that you have to buy your ticket in advance because tickets are not sold on board.
  • Some shops, restaurants and HSL ticket machines do not accept cash and only take card payments. In general, most payments are made by card. All major credit cards are accepted in Finland, but some merchants do not accept American Express. ATM machines are called “OTTO” and accept most international ATM and credit cards.
  • Tipping is not expected in restaurants, taxis, or other services. The service charge is already included in the price. However, tipping is not forbidden, and some Finns like to tip if the service or food is particularly good.
