This is a lovely little apartment. Perfectly clean, lots of natural light during the day, nicely equipped, nice hot water in the shower. It's very secure as well. The main entrance door is nondescript and there is a 24-hour front desk/security. The doorman Omar was lovely. The check-in process was smooth and easy. The rooftop was beautiful and I loved that there was an exercise bike up there.
The highlight is the location. Plaza de Santo Domingo is literally around the corner. I walked to el Zocalo and the cathedral, maybe half a mile, and to Palacio de Bellas Artes, maybe 3/4 mile. The area is lively and there is a convenience store on the corner and plenty of places to eat and shop within a few blocks.
Since the space isn't very big, I think two adults can fit comfortably and that's about it. I had a comfortable stay and highly recommend this apartment.
