Luiz and Mafalda's place was generally great but we ran into one large issue so I'll be as transparent and fair as possible.
First the positives. The apartment was very comfortable and was nicely decorated. There were ample kitchen supplies and the building was right on a main street. The train was a bit further than we expected from the apt but we walked most places and Ubers are widely available so the location was fine for us.
However, we ran into an issue where the wifi went out the first night so we spent three full days and nights with no wifi or TV/cable. This made it difficult to do any work and was very inconvenient.
To be fair, this may have been bad luck more than anything and to Mafalda's credit, she tried to find a solution. However the issue was never fixed while we were there for three more days and no alternative solutions were made available to us. The apartment has some strict rules to follow (not an issue for us) so we think it's fair to expect a quick response/solution to issues as well.
So overall, the apartment was great but unfortunately the wifi/TV issue happened. Hopefully the issue is fixed for future guests. Thanks.
