We stayed at Agatha's studio for two nights on the 1st weekend of March and we had a great time.
The pictures represent the studio very well: it was clean, we had enough space and the gallery was really comfortable. It was a little bit cold in there but we always turned on the heating for night and this way it was warm in the room and the bathroom too.
The location of the flat was perfect for us because it's behind Petrin hill so we were able to walk in the nature a lot. Those who don't like to walk that much can use the recommended bus from the description to reach the studio.
There was a city guide book in the flat which helped us in exploring Prague. And we had all the equipments we needed for our stay.
