My husband and I stayed here for a month while working remotely in Porto, and could not have asked for a better apartment. It was spacious, well decorated, comfortable and in a great location. The staff managing the apartment was very good about answering communications and very friendly. Having the washer in the apartment was incredibly helpful. We also felt very secure, as there's a very heavy duty lock on the front door. The only little thing was that the touch controls on the cooktop were a bit finicky, but there are so many great places to eat nearby it's a good excuse to go out :p
I whole-heartedly recommend this apartment and we will definitely stay here again next time we're in Porto!
