Our stay at Regina's was absolutely wonderful. We had a warm welcome despite the fact that our plane was delayed 2 hours, arriving quite late at night!
The building is new, the flat just perfectly modern, cozy and clean. She had prepared loads of information, tips, restaurants in the neighbourhood (definitely try Yam Yam or Café Záhorský for breakfast!), etc in spreadsheets, which made everything more enjoyable.
So close to the centre, it's just a pleasant 15 minutes walk to the amazing Castle that at night has a breathtaking view, making every late night walk home like a movie.
Already planning to return to Prague, and definitely staying at hers again!
