The apartment is super spacious and the number of bath rooms is more than enough :-) We appreciated the central location close to the river, the public transportation is just around the corner and you can walk everywhere. All communications with our host was very smooth, we got the keyes from the downstairs locker without problems. The Indian restaurant just downstairs is very convenient and good; also other restaurants closeby. Bagel and coffee shops very handy. We didn’t find any big supermarket (the minimarkets are really mini) very close so didn’t cook any meals at ”home” except for breakfast.
The old building is renovated with only rental apartments but it was quiet. Prague is such a beautiful city and the apartment very nice.
