Great place to stay, nice and quaint. As mentioned not very large but if youre out all day good place to stay. Enjoyed the quietness of the apartment I stayed at while right at the heart of la roma and obregon. Check in was easy and location is excellent if you want to get to know the real mexico city.
Only downside was the slow wifi. In case you need to do work or have to be online a lot, not the most ideal connection.
