We have had a very good time at Andre's place. Communication was fast and easy. I really liked the self check-in. We arrived in a very clean apartment. It is very cozy but has no windows except the ones integrated in the entrance door. The area is fantastic. In walking distance to Lisbon's best Fado places and other good restaurants (e.g. Alfama Cellar).
Only the high humidity is unpleasant. Probably you can deal with it pretty good with the right use of the dehumidifier.
However, a very good value for money overall.
