We stayed 3 nights with my family (5 adults) in Jan's apartment and we loved our stay. We were Jan's first guest but it was just perfect. Even though we didn't get the chance to meet Jan as he was renting his flat while he was on vacation, the communication with him was great, super friendly, giving useful indications to prepare our trip. He made sure we will have a great stay in his flat with lots of personal attentions on our arrival (wine, chocolates, book with recommendations and information, space left in the wardrobes for us,...).
The apartment is very spacious, nicely decorated, very personal as Jan leaves there with his family and perfectly located. The area is great with lots of bars and restaurant, art galleries and very close to the center and the main attractions.
I would totally recommend this place !!!
