This is a wonderful apartment.
The instructions to get in the house are precise and complete: we didn't have any issue in finding the place and getting into the house.
The house was perfectly clean and equipped with everything one may need for living.
Ceilings are a bit low, but absolutely comfortable unless one is really tall. We're 1.75 and we fit perfectly. They also give the house a charming and cozy look.
The house was warm, despite the cold outside (-16).
The position is just perfect, right in the old city, near the dome square, with many small markets at walking distance and a lot of nice restaurants to eat, at every price level. We had no problem in coming here from the airport: bus 22 + 5 min walking.
We'd definitely advice this house to my friends - in fact, we did it, as we've sent the link to some friends who want to visit the city :)
