It’s a big, cool, very old space. It is a good base for Porto, an easy walk to everything. We stayed on the weekend of sao João festival and had a great time. There is plenty of hot water, good wifi. We had our own separate toilet and the spaces are large. It was excellent value! I loved the cat cuddles every night. The room had a balcony and the place had easy access to all you need (washing machine, fridge etc)
Would recommend, but don’t expect your standard Airbnb experience. I would stay again if visiting Porto!
