Celestin was a great host, meeting me at his office when I arrived from the airport and helping my lug my bags up four flights of stairs. The room is spacious and very comfy, the only thing to be aware of is that it's right over a hugely busy avenue which is pretty noisy - if you don't usually travel with earplugs (like I do), then you should bring some. Apartment is super well located, with tons of nearby shops/bars/restaurants/transportation, and in a safe area. Celestin shared some mezcal with me, introduced me to his friends and was very friendly/communicative overall. Thanks for a great stay!
