We were 2 and came for 3 nights. Both beds were comfortable.
Madeline was kind, reactive and welcomed us late on a Friday evening (thanks again). The apartment is fine and clean. It is situated in the small streets of the beautiful center and very close to many touristic places, tramways, etc. Note that there are lots of stairs in this neighbourhood and that it can be a little noisy on Friday and Saturday night.
We really enjoyed our stay in Lisbon! Thank you Maddie for hosting us
