Looks as described in pictures though a little bit more run down in person. The location is excellent - close to walk up hill to main attractions, or down to the water front in a short amount of time. There is a small Spar at the bottom of the street for some supplies, and many restaurants nearby.
It is a noisy street, but you can close the balcony windows and put the metal coverings on and it gets very quiet - although all sealed up and without any environmental controls it gets very warm and stuffy at night. The space is ok for two people max really with the one bed partially separated from the living space. The bed is on a platform you climb up onto as per in the pictures and is extremely firm with a few very flat pillows.
We found communication was a bit challenging at times (hit and miss) around both check in and during our stay (there are issues with the key and front door). I always feel a bit skittish when a business service (TPC here) is responsible for your stay rather than a single host to contact as there feels less investment from a host/guest relationship. Maybe that's just my opinion/experience. I've AirBnB in Porto many times and this just wasn't the smoothest stay
