We really enjoyed our stay, and would recommend the apartment for others. It's extremely well situated in the touristic center of the city, has gorgeous view of the astronomical clock - while still keeping very quiet inside. It's very spacious for a couple (the images do disservice in this aspect!), cozy and well equipped. It has the pleasant feeling of an apartment people live in - it doesn't feel cold and sterile as some other central-positioned apartments; we liked that very much. The entrance to the building was a little hard to find - don't hesitate to contact Martin in such a case, he was quick to answer with additional details.
