I can only recommend this beautiful apartment if you want to visit Prague.
Even if the apartment is not situated in the very center of Prague, you can reach all the sites you like either by a few minutes walk (which I recommend because this is the way to discover the places of interest in Prague... and they are a lot of them, or you just can get the bus or tram which just stop in front of the house!
The apartment is very clean, modern and cosy decorated. You will feel at home from the very first moment.
Josef is the perfect host and he is always in contact with the guests in case of any needs. HYou will get lots of information in and around Prague as well as restaurants, bars, points of interest to visit. He is the perfect host and guide!
I can only recommend this house. You will love it!
