We stayed 5 days at Mark's apartment. It is a very big, but old apartment. Centrally located, within 15-20 minutes walking you are at Old Town Square. Tram stop just outside, and metro station 3 minute walking. Kitchen and bedroom are large, but bathroom not so comfortable. There was no soap in the bathroom. We had no heating the first two days, and on the third day Mark came to the apartment and fixed it. I recommend it, as it is in ideal location!
