Alê and António's place was perfect for our stay. It's everything you expect from the pictures, plus a lot of convenient amenities we never even expected. The area is one of the nicest and quietest in Lisbon, with great cafes and restaurants, and in walking distance to the gardens, attractions and museums in Belém. We were working from home during our stay, and the wifi connection was great in the entire flat - including the garden.
They were also always available to help, and had great recommendations for things to do. We'd happily stay there again :)
