I would recommend this place if you are going to visit Porto summer. Very stylish and nice decor. “Secret” door to the living room is a nice touch.
If you are visiting in winter or mid season as we did, be aware that this place actually does not have heating (or at least it may not work), we freezed both nights of our stay even after we told the the heating does not work the first evening, the host didn’t fix it the next day.
Note that the host is quite unresponsive, don’t expect them to help you after 6pm.
The windows in bedrooms seem to be not isolating the cold efficiently and they don’t isolate the noise well - I could not sleep because of the a/c split system fan rumbling at the balcony (not sure why does it do that even when a/c is off).
Check everything (including heating) works when you arrive.
