Lucila's apartment in Roma Norte is a great location. The 4 bedrooms were very handy for our family of 5 -- allowed us all to have our own spaces when we were in the place. The location is perfect -- walking distance to lots of restaurants, parks, etc...
While the location was great, there were a few things about the apartment that made our stay difficult: (1) no screens for the windows so mosquitoes were a problem for us (we recognize this may be common in Mexico City but want to give people a heads up); (2) the front door keypad malfunctioned and alarmed every 10 min all night long one night; (3) we had problems with reliable hot water (ie no hot water for showers for 1-2 days); (4) there is a club next door and on Thurs and Fri nights it was SO noisy (and we had to have the windows open because it was quite hot with them closed); (5) this is small, but one of the blinds wouldn't go up in the living room which made the front common room very dark. Just would have been more pleasant with some natural light in the front room.
But I also want to highlight that Lucila was VERY responsive and a lovely host. She tried to fix all of the things, and we were very appreciative. She also gave us some great recommendations.
