Marco is a great host, and this is a great apartment in Condesa. Just about a 5min walk to Parque Mexico, this apartment is in the most desirable part of Condesa (in my opinion). This area is safe, the apartment is in a secured building with only three units, and Marco lives in one of the units. There are great restaurants in the area like Botanica (just two blocks away), and there is a OXXO (convenient store) within half a block. It really is a great location.
The apartment is bright, has lots of natural sunlight, and is stocked with all the cookware you need in order to be self sufficient. I was working remotely, and the wifi was plenty fast for web meetings with no issues of continuity. There is only one TV in the bedroom (connects to your Netflix, HBO, etc. which is great), but not one in the living room. I am not a big TV watcher, so it was fine for me. Additionally, Marco has the apartment cleaned weekly by a professional who comes in and deep cleans everything. There are two bathrooms which are nice if you have anyone over.
I also really appreciated how quiet the apartment was. The apartment is the entire floor of the building and the bedroom is located in the rear of the building so there is no street noise whatsoever at night. The apartment has a good washer and dryer for you to clean your clothes with as well. Finally, the hot water can go out while you are showering, but it comes back on in a minute or two... However, I think this happens at all places in the area (because I have had the same experience at multiple apartments in this neighborhood).
