We loved our short stay visiting Porto at Alvaro's place in Gaia. Alvaro and his wife were so accommodating with a very last minute booking late in the evening. They had the place cleaned and ready for our stay within 90 minutes even though we requested so late, around 10pm. They made the check in process super easy and they are located in a great spot close to everything you want to see in Porto. We would definitely return and stay here, highly recommend!
