Alvaro was a great host. The house was clean and comfortable and there is free parking on the street.
You are in the centre of Porto within a 20 to 30 min walk. About 10 mins to the metro. It's in an elevated position so there are quite a lot of steps down to the main street nearby; Porto is pretty hilly so you will get used to that.
The weather was good while we were there so the garden was much appreciated.
