Had a very nice stay at Luis Carlo's place. This is one of many places that he and his team manage, so although it lacks some of the personal touches, it is well run and we were always able to get in touch with someone. The apartment is very stylish, clean and supplied with all the basics. The bed and linens are comfortable. The apartment is quiet as the bedroom is in the back of the apartment away from the street. The internet is adequate (about 7-8 mbs). The location is great. On elegant Avenida Vera Cruz. Metro stop Chapultapec is at your doorstep. Main streets of Condessa are about a 15-20 min walk as is Roma. Also an easy walk to the many museums in the park.
Only issue which everyone mentions is the hot water. It takes a while to come and then it comes and goes at random. We were fine with it and it wouldn't prevent us from staying in the same apartment again.
We would have no problem staying there again on our next trip to Mexico City and can heartily recommend it to anyone considering a stay. The photos and description are accurate.
