This was a great place to stay for 4 nights in Porto. The location is perfect and within walking distance to some great restaurants and sights.
The apartment itself was clean and spacious, however, as other reviews have mentioned, there isn't a great deal of privacy and limited headroom in the mezzanine.
The apartment is quite noisy and creaky (particularly the seagulls!) so would recommend packing ear plugs.
I would highly recommend this airbnb and would stay again if we come back to Porto.
