We loved Maria Rita's apartment! It is about a 5 to 7 minute walk down to the water, there are tons of cute cafes within minutes of walking out the front door, there is a large train station about a 15-20 minute walk away where you can take the train to Cascais or other little beach towns along the route, there is a peekaboo water view from the living room and front bedrooms, and overall feels nice and spacious.
There are 3 bedrooms, two of which have twin beds in them, plus a king size (I think) master bedroom and two full bathrooms which was great for our family. The ceilings are high, the apartment is light and bright in the afternoon, super clean, and Maria Rita is a wonderful and informative host. We would definitely stay here again in the future if we are in Lisbon.
