This apartment was great for exploring the Roma and Condesa neighborhoods and the city. It's a little bit of a walk from the metro at Hospital General but slightly closer to the Metrobus station there and even closer to the Metrobus station at Sonora. We were happy to treat it as a home base (and there are great street tacos as well as fancy restaurants nearby).
Jaime was a very responsive host and was kind enough to set up a driver to take us to the airport when it was time to leave. His father (also Jaime) met us with the keys and was very kind even though we were over an hour late because of a delayed flight.
The apartment was spotless and has everything you need. They even left bottled water for us in the fridge.
One small thing: the walls of the building are a little thin, and the apartment faces an air shaft with lots of windows, so we could hear other people in their apartments during the day and evening, but they never kept us up at all.
