Paty's place is great--we loved the natural light, calm ambiance, and location right on Mazatlan's pedestrian-friendly boulevard! People-watching from the living room ended up being one of our favorite things :) Mexico City is such a megalopolis that it was really a relief to find a spot that still felt like a getaway in a great neighborhood. It was easy to walk to local restaurants, bars, and shops (even found a gluten-free panaderia); to explore Chapultepec park; or to take the subway downtown or to other parts of DF. We had a group of 4 and the space inside was plentiful. Kitchen setup made it easy to fix a couple of our own meals. Loved the eastern accents throughout the place, meditation room, and inner terrace. Also appreciated the water filterer (so we didn't have to keep buying bottled water).
Couple things: 1. It was January and the space heaters at times weren't quite sufficient, one or two more would be nice. 2. Some of the dishes weren't quite clean so we re-rinsed and then had to wait to fully dry, which was a bit of an inconvenience. 3. The larger bathroom's water heaters went out after about 3 minutes a couple times, giving one of us quite a surprise--we weren't sure if we weren't using it right or if it only had that much warm water. The smaller bathroom's did work, though.
That said, Paty is a very responsive host so I imagine these aren't ongoing issues. Also let me reiterate that it's a great spot and we very much enjoyed our time there!
