Rafaela and Celio are extremely friendly. The apartment has absolutely beautiful potential to be a very romantic little spot for travelers. Also affordable, and in a cute location walkable to most sights and sounds of Porto. The little patio is delightful too - for standing. No furniture.
The areas of development:
1/The furniture and other effects need updating very badly. We had a broken couch. The other items in the apartment are just very, very old. They could spend a couple hundred dollars on some small updated items and make this place a dream.
2/Communication - there were a few misunderstandings during checkin. I asked if we could check in early and she gave us the entry info. Ended up in a very dirty apartment. She said she only intended for me to drop my bags. Okay.
3/Checkout is a bit complex. Very tired travelers might mess this one up. You need to take photos of the keys in different positions. It’s a lot.
4/There are no lights in the main hall. You need a flashlight to go up the stairs at night.
In all, it was not terrible, but I would not stay again unless they make the updates.
