The location is good. It is right next to a supermarket and a few restaurants. It is about a 15 minute walk into downtown Porto.
The room was excellent. It was clean and spacious and had a very nice balcony.
The only downside that needs to be considered is the amount of stairs you need to walk to get to the upper levels. The ceilings are really high (which is nice!) but that also means that to get to the "fourth" floor I was climbing about 6 flights of stairs. If someone has impaired mobility or small children this could be an issue.
