This is a truly great spot in Mexico City. Centrally located, it's easy to get to the two standout neighbourhoods in the area: Roma Norte and Condesa. We stayed here for almost two months and only took uber to visit other areas of the city - everything else is walkable, safe and with a ton of variety.
Being close to a busy street there is some road noise in the mornings, but this is part of the experience of CDMX -- from the honking as people commute to work, to the call for scrap metal (colchones, tambores refrigeradores..!), to the long high whistle of the camotes y platanos man, to the guy on the bicycle selling 'tamales, Oaxaqueños'. I don't say this to put you off, but to give you a sense of the thriving and busy culture of this city. If that all gets a bit much it's a short ten minute walk to Condesa for a quiet coffee or drink on leafy streets, full of purple blossom if like us you visit in March or April.
Marco is fantastic. He did so much for us during our stay that I'm sure I will miss something in this review. He arranged for his friend to pick us up from the airport, arranges a weekly cleaning service, even upgraded the internet for us when we found it wasn't fast enough for Netflix and streaming etc. The apartment is very well equipped and well looked after - we didn't have to buy measuring spoons or a grater like we find ourselves doing in some places.
The people of this city are incredibly friendly. We barely speak a word of Spanish, yet were never made to feel uncomfortable despite this being MX's capital city. The areas around Marco's apartment are very safe (statistically and from our experience) and full of interesting restaurants and cafes.
There's no air conditioning but we didn't need it - the fans cooled us down, despite some hotter days. He has a water cooler in the apartment if you want to avoid the tap water, although we ended up drinking it with no ill effects.
For such a long trip any review is going to miss our on something, so I'll just repeat the essentials: 1. Trustworthy host who genuinely goes above and beyond, 2. Apartment is as-described and all you could ask for 3. Location is hard to beat if you want both Roma Norte and Condesa, the two best neighbourhoods in the city.
Thanks Marco for introducing us to your city and making our trip so worthwhile. :)
