He was super responsive host and the place was extremely conveniently located: 3min to the tram/metro stations, 3min walk to the nearby supermarket/many restaurants, and 25min walk to the central market. 10min tram ride to the beach, then you can pop back on the tram with one easy transfer, you would be dining at Colon market in no time.
However, it may not be for everyone: the walls and ceiling of the flat were paper thin and you could hear; your next-door neighbor yawning, upstairs' footsteps are pretty constant till very late, next door neighbor's baby crying, and the windows didn't help keeping outside noises much at all. Also, it's very close to the university, many students were partying on the weekends, and surrounded by many eateries, which is convenient but also could be noisy especially restaurants open till midnight to even 1am. It worked for us very well because the noise didn't bother us that much, and it was only 8min walk to my daughter's flat
