I stayed in Eloi's room with a friend for 3 nights during a Portugal trip.
Everything was great. The room was clean, cosy, exactly as shown on the pictures and very well located to all the important things in Porto.
Eloi was super friendly, replied to my questions and even took some time to give us some good advices for the city when he welcomed us.
The only negative aspect was, that it was very loud in the streets around the room at night. But it's fine with closed windows.
I would come back again!
