We had an amazing time in Porto in Rui's place, I can't recommend it enough. The host is amazing, so easy to talk to and so helpful. They went out of their way to help us in any request we had. The rooms are exactly like described and can easily fit 10 people. The location is also pretty incredible.
To Rui I have to say, thank you for the great hospitality. you made our trip to porto really amazing. special thanks for providing us with the transportation to Lisbon.
