Great little place right in the middle of Historic Center. The place was exactly as described. Taxi from the airport costs MX$224 (Oct 2018). UBER back to the airport was about MX$ 85 at 6 am, could be a bit more during the busy part of the day. Small supermarket-OXXO, next door. ATMs about 5 to 8 minutes walk away.
We walked to all the historic centre attractions. Vegetarian restaurant is less than 700 meters away (Los Vegetarianos). We even found vegetarian options at the hole in the wall taco place.
As this place is bang in the heart of Centro, leaving the windows open at night can be noisy.
All in all, 100% recommend this place.
