This private studio really a very nice base for exploring Porto. Perfect location, recently renovated, good size for a studio, fully equipped and nicely furnished. Communication with the hosts was prompt and check in possible on very short notice.
The building has hardwood floors, so you do hear the neighbors and the upstairs folks, but nobody really made a lot of noise so it wasn't an issue for me.
Parking is available in public garage nearby for 17 euro per 24 hours (discount ticket provided by host).
