Stayed at Sofia's place from Tuesday - Friday during my Mexico City visit and it is just as cute as the photos, clean and modern and in a quiet and safe neighborhood walking distance to Coyoacan center. The penthouse apartment is comfortable and gets lots of natural light as well as has it's own very cute private patio and washer/dryer access. The space itself was lovely. Communication prior to my arrival and check in was great, prompt, and check in was a breeze. Unfortunately we did hit a snag the Second (Wednesday) night when I had trouble accessing any hot water as well as having the TV on at the same time as the space heater in the bedroom seemed to blow a fuse. This circuit also controlled the patio lights as well as the in apartment wifi. Luckily there were a couple of other weaker wifi options from other routers in the building that we were given upon check in so we were able to connect to one of those. I attempted to contact the host about the issues and figured she would get back to me in the morning...but nothing. I attempted to contact the host periodically through the day regarding this as ice cold showers are not quite ideal but heard nothing back for over 24 hours regarding either issue. By the time we did get a response it was the morning of our check out, she was very apologetic about the lack of communication and her mom was very nice and tried to solve the issue/call in a worker to fix it. I hope it got fixed for the people who checked in that evening, because it was not solved before we had to check out and be on our way. Also, if you stay here make sure you hit a store and grab yourself some water before arrival...the check in paper said a water jug was provided but there was not one. When I asked I was told that was for the other units in the building which apparently they also rent out (and apparently do come with provided safe drinking water) which I thought was a little strange as having water would have been a nice touch.
