We stayed at Arcelia's for a full week and had an absolutely amazing time. The space looks exactly like the photos and will be everything that you need; it started to feel like home every time we came back from an outing. There were two lovely gentlemen who were always there in the morning and evenings to let you in and out of the building. We always felt extremely safe and comfortable.
The building is centrally located and very close to the Condesa and Roma neighborhoods. You can take a leisurely walk or easily catch an Uber to get to any of the city's many attractions in just a matter of minutes.
Arcelia was also great with communicating and answered any questions that we had and even suggested neighborhoods and events to visit. I would definitely recommend Arcelia's space to anyone looking to travel to CDMX :)
