Really nice apartment on a busy/cool street. Lots of room if you have a few big bags on your trip. The stairs hurt barefeet but its not a big deal. Its a huge spot for a city, and the downstairs bedroom is very quiet at night. You can kind of hear a train but its not bad.
The heating system is a bit complicated and recommend you have the host explain it to you. The heated floors are awesome in the morning, but not awesome later in the day :)
