The biggest benefit is the location, but if you are gonna stay in Porto more than 2 nights, I would consider other place. Appartment is smaller than it looks like from photos, bathroom doesn’t have ventilation so you need to keep the windows open, but then it’s super noisy from the street.
The biggest downside was missing wardrobe, so our clothes ended up all over the place.
Neverheless we had nice stay, the location was just great and communication was spot on. Thanks!
