We (group of 6 friends) had a fantastic time at the apartment! It is even more beautiful than described and definitely worth booking. Location is perfect to get around Porto by foot. Can recommend also to have drinks at the craft beer garden and enjoy Mexican food next to this building. Communication was super easy thanks to Ophélie.
Depending on the length of the stay and group constellation, 10 people might be a bit heavy, because 4 would've to sleep in the living room. The couch/bed construction is super cool though and as unique as all of the furniture.
5* in every category :-)
