This is a clean, cozy apartment in a prime location in Alfama. The woman who checked us in was very nice and extremely helpful with details about the apartment and about what to do in Lisbon. The hosts were kind enough to provide a small snack and bottle of wine, as well as coffee for the house, which were all very appreciated.
The main floor and main bathroom are very nice rooms to hang out in, with enough space; the rest of the house is a bit cramped. We were able to fit 6 people in here, in 6 separate beds; but 8 would be too much in my opinion. The upstairs has a very low ceiling, so only 2 of us were able to use it. The downstairs bedroom spaces are mostly taken up by beds. I think if you are not worried about the space in the bedrooms and upstairs, it's a great apartment in almost all other ways.
The doors in the apartment are having some problems. The two doors to get in the apartment were hard to unlock with the keys (you have to position the key just right, and initially during check in we spent 5-10 minutes figuring this out). However, during the first day of our stay they came to fix the inner door. So they were very responsive to the problem (the outer door is still a bit misaligned, but once you figure it out it's easy to open). However, the doors to the bathrooms are also in need of fixing. The main bathroom does not have a lock, and the bathroom in the downstairs bedroom is unable to close.
The wifi did not connect in one of the rooms downstairs, but was otherwise fast and easy to use.
The location was great for us. There is a street close by where we went to some Fado places, and it's a 15-minute walk from the main, historic center with lots of shops, restaurants, bars etc. It's similarly a 15-walk from a very nice view over Alfama (getting there is kind of fun, through a bunch of back-alleys in Alfama, you follow the stairs upwards).
Overall we are very happy with our stay and we would recommend this apartment to anyone else who is looking for an affordable and cozy space to sleep during their stay.
