This was definitely one of the nicest places me and my parents stayed at. The studio is as nice as on photos, everything clean and new, in the city center so everything is walking distance.
Jéssica and Mariana are amazing hosts, very welcoming and friendly, told us lots of useful information about the city. When they say that they are your friend in Porto, they really mean it. If you have any problem or question you can always write to them and they will help you, which is very nice considering that many hosts just give you the key and disappear.
I would definitely recommend that place to anyone!
