I would definitely stay again in Anna's flat. Bigger than it looks on the pictures. This flat is confortable, clean and very light full. The little balcony is very pleasant. Also the location is the best I could have. Just btw the castle and Charles bridge but not as busy (also it was raining when I was there). The bed is very confortable.
Thank you Anna for being such a good host and make the things as easy. I recommend this Rbnb.
