Dave's place is absolutely as beautiful as the photos and was a great home base for us to explore Mexico City for the first time. There's a lovely amount of care and detail into decorating the space and making it feel homey. I especially loved sleeping in the loft (although there's no guardrail, so don't be scared of heights!)
It's a quiet courtyard off a quiet street, and there are few if any other tourists in the immediate area--if you're looking for an "authentic" experience it's perfect, you're literally living with locals--but it's a short walk up to the Zócalo or over to Bellas Artes, and there's plenty of action just a couple streets away (seriously--a boombox and stereo-equipment mecca, and it just gets more interesting from there). Dave gave us a few recommendations on places to eat and explore :)
A helpful note--be sure to brush up on your Spanish before you come here! Almost everyone we met barely spoke English, but we managed to get by on a grade-school level of Spanish vocab, and everyone we spoke with was so friendly and helpful working around the language barrier.
We highly recommend exploring this beautiful city, and highly recommend staying at Dave's place when you do!
