My husband and I stayed for two weeks during the winter, we had a great time. The apartment is beautiful, luminous and spacious. It was also nice and warm with good beds and a wonderful kitchen. The place has a cozy feeling that was great as we stayed for many days away from home. Katja´s father Sasha was always very helpful with the check in and check out process, and during our stay he answered promptly any questions we had. I recommend this place for a stay in NYC if you need to be in the upper west side.
