The Blue House's apartment was the perfect spot for my friend and me during our time in Lisbon. The apartment is spacious and clean and has all the amenities one could need for any length of stay in the city. The building is in a prime location. It is in walking distance to all the sites and close to supermarkets, nightlight, and restaurants. And right at your doorstep is arguably the best bakery in the city -- with over fifty locations so far. Definitely try any and all of their baked goods and breads. And their coffee and juice is great, too.
Communication was easy and simple. Everyone was extremely responsive and helpful and wanted to make sure we enjoyed our time in Lisbon. The hosts even helped us book transfers at fair prices.
When I come to Lisbon again, I will definitely stay at one of their apartments. 10/10.
