Not only is this a great apartment but it sits above a perfect little café, bar and club. The apartment itself manages to be simultaneously spacious and cosy/romantic, retaining lots of old Prague atmosphere but with a nice, modern bathroom.
Communication with Lenka and Jaroslav was very quick and friendly but unfortunately we didn't get to meet them (check-in is via the café downstairs).
As for location, you are perfectly situated just around the corner from the Mala Strana end of the Charles Bridge where you are spoiled for a choice of bars and restaurants.
All-in-all, we loved our stay here and will definitely return!
