Santiago's apartment is very near to a Subway/Subte station (and Subte is very convenient and cheap in Buenos Aires). The apartment is exactly as described and shown in the photos, very comfortable, design/architect touches, functional kitchen, washing machine, 3 AC units throughout the apartment, nice sound system & TV, etc.
It was extremely clean upon arrival (do not see such cleanliness that often!), towels wrapped, etc. - very nice to kick-off holidays.
Santiago si extremely responsive and accommodating, and above all genuinely generous when looking after his guests. Definitely recommend!
