Joesf's flat is just incredible. It was even closer than I thought it would be to the Old Town Square (3 minutes walk) and it was a lovely, bright space. The beds were really comfortable and you have everything you needed. The information provided by Josef was great and we really enjoyed the coffee and pastries from the cafe downstairs. The only tip I would give to people who are light-sensitive when they sleep is to bring an eye mask as the curtains / blind still let in a reasonable amount of light (I did have an eye mask but my husband likes it light so he was happy!)
Josef's communication and response time is really incredible and nothing was too much trouble. I highly recommend this property and if I return to Prague, would definitely stay here again.
