Matias was super easy to communicate with and really flexible in allowing a slightly later check out. The place is lovely - modern, clean, well set-up, nice little quiet balcony. Location is also excellent for buses and a few minutes walk for metro. Area felt safe and had a great vibe and Recoleta graveyard only a few minutes walk away. Would highly recommend it. Only thing I would add about apartment is walls are super thin so you will hear music (and other night activities ...) clearly from your neighbours. Was absolutely not a problem - all was quiet very early and didn't have any noise at all after about 9pm.
