My wife and I really enjoyed the apartment. Although its fairly central, it was quiet and relaxing. The apartment is clean, modern, comfortable and tastefully decorated and very warm (despite the coldest winter in Prague in a long time). The host was extremely quick to reply when we needed him, and was flexible with us when our flights were delayed.
The apartment is only a two minute walk from a Tesco, and there are great restaurants just over the river, a few minutes away.
