Staying at Maria's place was a great option in Prague. It was a walking distance from everything, the only time we took the tram was to go to the castle, but you could walk there if you wanted to. At night we also felt safe around the neighborhood, that had many places to eat and supermarkets. Maria was there to receive us when we arrived and explain everything, offering to answer any doubts we might have. Also, the apartment was very organized and clean, with all new installations.
