We had a great time here! We were with 5 persons and had enough space. Especially the location was perfect! We did everything by foot. It was also a quiet apartment, because it's on the third floor you don't hear much noise from outside. The only disadvantage about the apartment is the shower, you have to hold it yourself, and there is no shower curtain so with 5 people the bathroom can get pretty wet.
Petr picked us up from the airport as brought us back for a bit cheaper then a regular taxi, which was really great. When there was no corkscrew Petr brought it to us the next day.
