It was an amazing stay in Prague, and part of the amazingness was because of the apartment.
Location: It is perfectly located near the center, but still in a calm street that supports a deep and quality sleep. There are many great restaurants and cafés just 2 minutes walk. Supermarket and a park, river with its weekend markets - it is really 5 minutes of walk with kids.
Apartment: The apartment has everything that a person might need. Comfy beds, very stylish furniture, great view on the opposite old buildings.
I can't recommend it enough.
