Olivier is a great host! We didn't get the chance to meet him in person but we got many advice from him before we arrive. And he also left us welcome letters with bascially everything we need to stay in the house and get round Mexico city, which was really helpful for first-time-Mexico-travellers like us. We love the house a lot and enjoyed our staying there. It's clean, comfy, well-decorated, with amenities just as described and feels like home. The terrace was beautiful and we wish we'd have spend more time up there. The location was awesome, with almost everything we need within walking distance -- convenience store around the corner, decent restaurants next street, metro station, landmarks like zocalo, museums and post office etc. And we felt pretty safe walking around there in the night. There was a pub downstairs and was close to a commercial pedestrain street which made it not that quite in the night. But we were there on the new year's eve and we were totally fine with it.
