The apartment was good value and met our needs for a 4 night stay - it is very small with limited natural light, but we were aware of this before and knew we wouldnt be spending much time at the apartment. It is up a very steep and cobbled hill, so was tricky to get a suitcase up, but we managed. Would be less suitable for those with lessened mobility. Apartment was very clean! I don't think it had air conditioning which wasn't a problem for us as it was cool in March when we stayed.
Great communication from the hosts, and appreciated their tips on luggage storage and navigating the metro.
The location is very central, near to Martim Moniz square which was good for us and close to Baixa. However be mindful that it seemed to be in a slightly more run-down neighbourhood, and we felt a bit wary walking around the nearby area at night. It is not far from more brightly lit/busier aeas though.
Unfortunately the apartment was extremely noisy during the night with the people in the apartments above us, and woke us up every night. There is little sound proofing and the walls are very thin and you can hear anyone / anything in the street outside, and the people above, so if you stay, bring ear plugs!
Overall a good value apartment which met out needs, but with some noise disturbance, although not the hosts fault!
