Diogo and Ricardo are great hosts. Their unit is immaculate, centrally located in a walkable part of town with access to food, transportation and public amenities.
The unit is great for a small family with plenty of space and quite for young children. Located in a pedestrian only walkway, there is no ambient traffic noise.
Diogo was always accessible and attentive. The neighborhood is very touristy however, Lisbon is a small enough city where everything is accessible by foot or by a short taxi ride. Even the touristy nature of the neighborhood is not as overwhelming or silly as comparable places you find in San Francisco, London or Paris.
Highly recommend the Frames House.
