My week end was fantatstic and it's linked to Albertino. Its flat was really perfect, better than in picture, with an amazing from the 8th floor.
I was just afraid about the location, not exactly in the city center, but in taxi, it costs only 6€ to go to Bairro Alto.
Flat perfect, with towels and everything you need. And with Albertino, we had private mini bus to come from airport with very cheap price.
I will recommend to get in contact with Albertino if you need a flat in Lisbon
