The owner of the flat is really nice, she helped us find the right address and recommended a great pub with local delicacies. The location is great, the house is placed near a tram line and two metro stations. It takes about 10-15 minutes walking to get to the old town.
The apartament isn't big but there is enough place to relax. The bathroom is small but it did not disturb us. I think that it is a good place to reside if you want to see Prague.
