Fantastic place, hosts met me to let me in and make sure I knew how to get in and showed me around, then left me alone to enjoy the apartment which was clean, comfortable, quiet, and very conveniently located - it is literally right around the corner from the metro / underground line which is handy to get into the city centre- from memory it usually only took around 13 - 15 mins. Roman is a friendly and approachable host, and I highly recommend their place to anyone looking for a nice and convenient place to stay while visiting Prague.
