My boyfriend and I stayed here for about 2 weeks and this studio flat was perfect for our needs. My boyfriend was working remotely and the internet connection worked well for him (Zoom meetings, email, web).
The flat itself is pretty well-insulated from the city sounds outside due to the garden; I am a very sensitive sleeper but had no problems getting a good night's rest. The only noise you really hear are the occasional siren and maybe footsteps from the home upstairs (minimal). Carlos kept to himself, we saw him occasionally in the garden, and he communicated well via AirBnB messaging. There was an earthquake while we stayed and he messaged us right away to check in, which was very thoughtful. It knocked out the wifi for about 12 hrs, but he was very communicative about the repair. Couldn't ask for more.
We enjoyed the location a lot, as it felt very safe and walkable to other areas in Roma, La Condesa, and Zona Rosa. The garden is very pleasant and well looked after.
The space is exactly like the photos and well appointed with everything we needed for a 2 week stay. The kitchen is stocked with cookware, dishes, etc. and a very nice gas range and oven. Carlos also included a hairdryer and iron/ironing board, which are things I seldom bring but found very useful, and gave us fresh linens halfway through our stay. We would stay here again when we return to Mexico City.
