Gus seems a really nice & genuine guy, the flat is very clean however staying at the apartment was somewhat awkward. Gus wasn't really around & one of his friends was staying in his room. There was lengthy waiting times for the bathroom. I would suggest fixing locks to the bathroom door and looking into the hot water supply as the hot water for the shower didn't last very long. Bear in mind the apartment is on top of a hill & its approx. 15min to walk to the metro & then 10min on the metro to the centre.
