We had a great stay in Prague at Ewa's apartment!
The apartment had everything we needed and has an amazing view of the museum both during the day and at night. It's within walking distance of a lot of the main areas of the city, and also easy access by public transport too.
Ewa came and met us to give us the keys and show us round the apartment. She was very friendly and also gave us some local recommendations and pointed out where to find some things which was useful. Would definitely recommend staying here. Thanks!
