I had a great time in Ricardo's and Silvia's modern airbnb, which is located in a very peaceful street and yet only a few minutes away from the Luís I Bridge. In other words, it only takes a few steps to enjoy everything Porto and Vila Nova de Gaia have to offer.
Ricardo and Silvia are very reliable hosts and the flat itself is very comfortable and quiet (both at night and during the day). I felt at home immediately.
In short, I wholeheartedly recommend this flat for anyone who plans to explore Porto.
Thanks again!
