We loved our stay in Rui's apartment. The apartment was beautiful, spacious and we'll equipped. The location was also great - walkable (downhill) to all the major sites, and an easy and cheap cab ride back up for weary legs.
The apartment is stylish and in stellar condition and was very clean. The folks from Feel Porto were also very helpful with tips upon arrival and were very responsive in communication. They were especially helpful in helping us figure out a way to store bags to bridge to a later flight.
I highly recommend this apartment. We will stay here again on our next trip to Porto!
