We did not meet Vincent, but Lindsey and her friend were both very friendly and helpful. The room itself is large and clean, and perfectly located. All the major interest points are withing walking distance and it's so central you can easily go back to the apartment during the day for a quick break! There are plenty of bars, restaurants and shops nearby. The street is rather quiet during the day but can be a bit noisy at night, but this is not a problem if you have ear plugs. We really loved our stay in the beautiful Prague!
