Stayed for 5 nights. Juan was a very flexible and attentive host, meeting us at 1:30 am and proactively checking in on us during our stay to make sure everything was ok. The apartment is as described and wonderfully located in Alfama.
We had some issues with the bathroom that were out of his control but Juan did everything he could to make our stay comfortable - thanks for that!
Definitely recommending if you don't mind staying in an old building that comes with its challenges and quirks.
