Had an excellent stay at this house. The location was perfect and in close proximity to plenty of restaurants and cafes. Alfama is beautiful and it feels like you are staying in the real Lisbon here.
Communication was really good with the local host, Matteo. The key box was a bit fiddly to obtain the keys on check in and the door was fiddly too at first but once we mastered it then it was fine.
I would definitely recommend this place but bear in mind that the property is in an cobbled area where you have to walk up a few steps etc to get to it but we found it absolutely fine.
