Absolutely great appartement : brand new, the main room is very big and we were very confortable for having breakfeast at 3 couples + one child. Tee, coffee, milch, even a fresh bottle of wine and beer are provided as a welcome gift, so nice ! Tee and coffee in every room, and great bathrooms.
Maria was very nice, let us check out late as the next night wasn't booked. There is a map with every information, umbrella provided.
The location is great, 5 minutes walk from Charles bridge and 8 from city center. 3 minutes from Tesco, or small restaurants that are very nice for breakfast.
I would recommend it without any doubt!
