Me and a friend stayed at Sona's place for 4 nights and had an excellent experience. The apartment was clean, spacious and was really well equipped for anything we may have wanted to cook/eat etc. Sona was kind enough to meet us at the apartment from a late flight which we really appreciated. The location was perfect for us, it was quiet at night and we found some great local restaurants that were away from the tourist crowds but we were also able to get to anywhere in Prague within about 20-30 minutes using the easily accessed public transport network. Would definitely recommend this place for a chilled city break!
