Espoo is often ignored in favour of Helsinki, but it does have some interesting things to offer you when you are staying in an Espoo hotel. EMMA, the Espoo Museum of Modern Art is an excellent facility and should definitely be on your itinerary. You can tour the Espoon Kartano, an interesting old manor house which has a fascinating history. Lake Bodom is beautiful and a great place to spend an afternoon.
Travellers staying in Espoo hotels can take advantage of the great transport that Helsinki provides through the whole metro area. Helsinki-Vantaa International Airport is a world class airport that is well connected internationally. From the airport, getting in to town is a simple matter of taking a bus or a taxi to the city centre. The Helsinki commuter trains travel through Espoo, with the E, S, U and Y trains taking just 25 minutes, to get to Middle and West Espoo, and the A train taking 17 minutes to get to east Espoo.
