Very good location near the riverside area and close to Sao Bento train station and metro stop. Most of the main tourist sites are within walking distance. Useful services are all nearby: grocery stores, liquor stores, pastry shops, etc. I enjoyed staying at the apartment and would consider staying there again. Given the level of noise in the street, the sound-proofing of the apartment is amazingly good. I found the bed comfortable. The bathroom is small, but perfectly adequate. Note that there is no sofa — the wing-back chairs are comfortable. I was in a 2nd floor (for Americans 3rd floor) walk-up. If you have any mobility issues, take this into consideration. But of course, if you have mobility concerns, you need to investigate Porto very carefully, as it is a very hilly city.
