I have been there for 6 nights while I was looking for an accomodation. The place is located near the metro Marques de Pombal, which was a strategical place for me.
The house is quiet, the kitchen well furnished, all good also in the bathrooms. The condition of the sleeping rooms (at least mine) however, is not so good. The furniture is very poor, or better said totally absent except for a tiny desk, a shabby chair and a mirror leant on the ground. So you don't know where to put your things. Conversation with the host was quite good, even if he didn't always reply to my questions. I think this is ideal place if you are looking an accomodation for not more than 2 nights.
