We had a great stay at Carlos & Marisol's airbnb in Roma Sur. The location is fantastic, with everything we needed in close walking distance. There were a lot of great shops and restaurants on the block that we stayed, a grocery store just a few blocks away, food markets, etc. It was a very nice walk from the location to restaurants in Condesa, and up to shopping in Juarez just north of Roma Norte. We were able to get ubers very quickly to go to places that were a little farther away, like El Centro and Coyoacan.
The hosts communicated everything that we would need before we arrived, including the code to enter and Wifi. They reached out close to the arrival date to find out when we would be arriving.
When we arrived, the guard at the front desk had a note with our names on it, and let us in. The code to the unit was easy to use. The unit was exactly like the photos. It looked and smelled very clean when we arrived.
As others have noted in the reviews, there was some noise from outside - dogs barking, music playing, people shouting. This is to be expected in the center of such a busy city. We did not have an issue with the noise - I played white noise from my phone, and my friend used ear plugs.
The unit is pretty large. There are two sitting rooms on either side of the kitchen area. The large bedroom in the front has an en suite bathroom and a very large bed which easily sleeps two adults and maybe even a small child. The bed in the back room was smaller, but still could sleep two adults of average or small size. The bathroom for the back bedroom is just outside the bedroom. The two bathrooms are in between the bedrooms, so there is a good amount of privacy between them.
We were happy with our stay, and would absolutely stay here again.
