We really liked the apartment and the location of it in the centre of Porto! Everything is within walking distance. Opposed to some comments we slept very well and the mattress is comfortable.
Unfortunately there were some bad points too:
The view from the balcony isn't nice at all (wich you can't see on the photos) and it is not very well cleaned.
Also we wouldn't recommend to cook in the kitchen since some supplies are missing and the kitchen is very small.
The communication with the agency wasn't good either.
