We enjoyed our stay at Amelia & Marinho's place a lot. The apartment is small, but very nice and super clean. The bed is really comfortable (not always the case on airbnb).
The location is also great - close to the hip lxfactory and more traditional local places too. It's very well connected - tram 15 takes you to the centre and to Belem. There's also a big supermarket nearby and many nice restaurants.
Highly recommended!
