Very good location, right in the heart of Porto. Nice building, I particularly liked the stairway, it had a victorian feeling.
The instructions were very detailed, Olivia wrote everything we needed to know in the messages.
It was a bit cold (since the building has tall ceilings and we visited in late December), but we had an electric heater (which helped us with the heating of one of the two rooms).
The bathroom was also nice and clean.
For the location and the amenities, this was a very good deal and I would definitely reccomend it
