We spend 5 perfect days thanks to all the good advises given by Eloi! Restaurants, place to go, shopping areas, local tips: he forgot nothing and he spent more than 20minutes explaining each things to do :) the location of the flat is perfect, really!! Moreover the place is very well allocated in order you do not feel in a tiny place! I will definitely recommend to stay in this specific flat (that is oriented in the backyard and has a little balcony) because it is very quiet compare to eloi's others studios that are oriented on the street (more noisy)! In one word: GO! And enjoy Porto!!
