Maria's place is lovely inside and has nice views of old buildings and beautiful skies. It is in a great location with quick access to restaurants, shops, internet cafes, public transportation (bus, train, taxi). A few nice extras: there were two types of cereal provided, milk, orange juice, some tea, some coffee, sugar, also tips about local activities. The check in and check out process were easy, and Mylene was wonderful to deal with from beginning to end. She answered questions we had about the area, checked in to make sure all was well, and even booked a taxi for us the night before we left.
The one potential issue with this places is street noise at night, sometimes going well into the morning. There are several restaurants near by, and because the custom is to eat dinner late (starting at 8-9) and say out late, there was quite a bit of noise at night that continued into the morning on some nights. Street noise will definitely keep you awake if you are a light sleeper and plan on you plan on going to sleep before, say, 3 am. My husband, who is a light sleeper, had a hard time sleeping every night. I had no problem but I sleep like a rock.
