Loved my stay in Álvaro's house. It has everything you need.
Álvaro is a really nice person and allowed me to use his products (bathroom) and everything in the kitchen (drinks, food).
The house is as you see it in the photos, a really nice apt. in Bairro Alto.
Sleeping is not a problem at all, because the bedroom is in the back, so if you close the kitchen windows and (needed on friday and saturday nights) the doors that will bring you from the corridor to the bedroom, you will not hear a thing, even in the most busy night.
The house remains really cool even in september, and this is a thing you will definitely consider if you are travelling in Lisboa in the summer.
