We stayed in Porto for 6 nights in 2 of Luis's apartment, floor 3 with our daughters and then floor 4 when they left. Both apartments are beautiful and stylishly renovated in a perfect location. Close to train station, lovely park, supermarket, book store, gelato shop, and wonderful restaurants. Also close to many tourist attractions eg tower, university, museums and churches. Porto is a wonderful city to explore on foot, we walked regularly to the river and around the city at night which felt safe at all times. Luis was most helpful and quick to respond to all our messages. I highly recommend Luis's apartments when staying in Porto.
