The place we actually stayed did not look anything like the photos at all, it was a totally different apartment (although much bigger than advertised, so not complaining). Plenty of light in the main room. Internet mostly worked, but sometimes cut out for a minute at a time.
However there were some things that were not so good, such as an unpleasant smell in the kitchen (and even a toilet and shower in the kitchen, for some reason!), and no furniture in the bedroom except for the bed and a broken TV, so nowhere to store clothes etc.
The location is in the beautiful Juaréz district with plenty of street food and nice cafes and bars nearby. Downstairs is a co-working cafe with excellent internet.
