Manuel met us at the flat and check-in/check-out were easy. The flat was great--plenty of space and amenities (full kitchen, iron, hair dryer, TV, etc.). Stairs are steep leading up to the flat, like mentioned, and coming out of the flat, watch your head if you're tall. The place was in a good location in Bairro Alto and walkable to most sights in town (though, it is a very hilly city!). Like other reviews said, it can be one big party in the neighborhood through the night, mainly the weekend. We were in Lisbon for a wedding, so we didn't mind the party atmosphere :) The windows do block out the sound very well.
