The place is splendid! I highly recommend it.
We were able to check in 1 hour earlier, the hosts were very flexible and helpful. Cristina greeted us herself and recommended lots of places and things to do in Porto. She's very welcoming.
The place itself is beautiful! I wish we could live there, it feels like home. The apartment is a perfect mix of historic and modern design. The location is also very nice, you will have beautiful and sunny view to the river from the balcony.
