I had a lovely time staying at Beaux Arts! José is a helpful, communicative host, and met me upon check in to walk me through the apartment. He was responsive to any questions, and provided lots of suggestions for what to do in the area.
The apartment itself is lovely, and to be able to work remotely from the small terrace was a dream. The place is, quite literally, a 15-20 minute walk from anywhere you'd want to go in Porto, on either side of the river. The neighborhood is quiet and close to many different cafes. When I'm back in Porto (And I hope I will be!), would undoubtedly stay here again.
