Sergio's place was very well located - close to the Central Market and cathedral etc. We walked om the apartment along the dry river bed to the arts & science complex & walked back through the city. Metro 10 mins walk away so the apartment was handy for the airport & beaches. Sergio was very friendly, communicative & helpful. The key hadn't been left in the arranged place so we had to call Sergio who came immediately & was apologetic. Apparently the new cleaner didn't know about the key arrangement. There were some issues when we arrived which may also have been due to the change in cleaner, but Sergio dealt with them straightaway - delivering a new duvet, duvet cover, bath mat & toilet rolls. There was a smell of drains so Sergio brought some air fresheners & we found that by covering the shower drain with a towel the smell was suppressed (the shower was in the bedroom & the smell was strong there). No other reviews have commented on the smell so we must have been unlucky.
