We had a wonderful time in the apartment. It offers everything needed during a city trip, and I couldn't think of any better location to visit the old town (it's near/in the jewish quarter). Since one cannot park the car nearby due to the spaces being reserved for residents, we followed David's helpful advice to park at Garáže Letná which is cheap, spacious, and clean.
David was really helpful and kind, the check-in/check-out experience was great. I can definitely recommend this accomodation and would go there again.
