Great location! Close to all the main tourist attractions which are all within walking distance. Has all the amenities that was listed in the listing. I stayed here for just under a month, so it was a nice bonus being able to cook my own food (place has a stove and oven). There are self serve laundromats closeby, but if you don't mind walking 12-15 minutes, I recommend going to Laundry Break Ice. It's significantly cheaper than all the other laundromats.
A thing to note, like others have mentioned, the noise level is bad at night because there is a bar directly beside/underneath the place. I had to use earplugs. Even with the earplugs, I could still hear people (noise level from 11pm - 4am). The bar is closed on Tuesday evenings (so, if you stay on a Tuesday evening it'll be quiet).
Overall, I highly recommend short stays at this location as it's a prime location for exploring Porto, has easy check-in and check-out, and the space is clean and spacious for two.
