Perfect location to visit beautiful Prague. Close to the main tourist attractions and at the same time placed in a very quiet area with several good restaurants /my favorite is Ungelt/. The apartment is impressively clean, tastefully furnished and has everything you need for your stay. A special advantage is the presence of both balconies /located east-west/, because you have sun and shade at any time, and keep in mind that during the summer months it is very important. And from the one to the west there is a great view.
We didn't have a chance to see Josef, but what he offered as a service from the moment of booking to our departure suggests that this might happen on our next visit to Prague. :)
