We stayed at Room no 2 for 2 nights. This is basically a Guest house in a fantastic location in Porto, just near Clerigos tower, in the lane next to Flying Tiger Copenhagen shop.
It is walking distance from Sao Bento station - exit the station, go right and then go left up the slope passing the Intercontinental hotel. All of Porto is hilly and lots of slopes, so 1st day you will have to drag your bags up the steep 200 m slope. We did it so you should be able to manage.
The outside of the guest house looks very shabby, but once inside it is fine. The family that runs this place lives on the ground floor and they are always available. The man of the house was a superb and friendly chap. There was no kettle in the room, and we asked him if he had one. He went into his office and kindly gave us a new kettle instantly for 2 days.
WIFI was fast and free and very good. bathroom was attached with the room and clean. There were enough towels, soap and pillows. Also a TV with cable!
Room was however not as bright as the pictures. It is a bit rundown from outside and tired looking from inside. The other major drawback of this place is also its is biggest positive - the location - bang in the middle of everything. And because of this, it was very noisy, even at night, and even with the windows fully shut. This is of course not the host's fault.
For the value that this place gives it is excellent. You can't beat the location. Don't expect anything fancy, it is clean and very basic with all amenities. I can recommend this place as value for money.
