We really enjoyed our stay here, the apartment is lovely and stylish in a cool part of Lisbon. The place feels both old and modern, which gives it a super nice feel. It is a bit small in terms of the lounge but as it can only sleep 3 people anyway this shouldn't be a problem.
Check-in was really easy and the hosts are super responsive and helpful. They even provided free wine as a greeting gift which was a nice touch, while we were also able to store our bags in their storage room which was great!
The area itself - Mouraria - has a lot of character and to me feels like a proper area of the city rather than a super touristy one, although I'm sure it will eventually undergo gentrification. It is a bit rough, which didnt bother me (I'm used to it living in London) but my mum was a bit unnerved at points.
All in all a great stay and I highly recommend!
