The apartment was close to the underground (~5 min walking) and spotlessly clean on arrival. We found it very similar to the pictures. It has a good distribution, with 2 bedrooms on separate floors both and a large dining room in the opposite side of the flat with access to a patio/garden. No problems on check-in or out and fast responses. The location is not central, but this gave us quieter nights and in any case it's very close to public transport and well communicated with Uber (a ride to the centre would be ~4€). We also walked a couple of days to/from Principe Reial in ~20 min.
We had a great time in Diogo and Joana's apartment and would definitely come back on another trip to Lisbon. Thanks!
