Elena (Helen) and Francisco were fantastic hosts, and the check-in process was great. This apartment is very modern and has great amenities. The location is perfect, off a fairly quiet street that's under a mile walk to almost everything in Condesa/Roma Norte areas. Some areas of improvement are the small-ish full-size bed, and the hot water in the shower was very finicky. Sometimes it worked perfectly, other times it didn't get hot at all. Some tricks that seemed to work such as opening the utility room door to the hot water heater - weird. Helen was very quick to respond to our concerns about the hot water, which was greatly appreciated. But there were a couple of days we had to skip showers because the water was completely cold. English is not spoken much in this area, so fluent Spanish speakers are recommended. Overall, an excellent place with just a couple of minor issues.
