We had a really nice stay at Ana's apartment. It's small (especially the bathroom) but there's everything one can only need. It's located in the centre of the Alfama district so it couldn't be any better. Ana is very friendly, our communication was great. There was no problem with the check-in/check-out, even though our flight to Lisbon was a bit delayed. The only thing that bothered us a bit were the noisy neighbours above but you obviously can't control that. In general, we recommend Ana's apartment to all couples that are planning to spend a few days in Lisbon!
