Ricardo is a good host, responded quickly and was there to greet us and gave us some local recommendations and a map. The place was clean and neat. La Condesa is a great area though with some traffic. If you're a light sleeper you may want to bring ear plugs... The apt is quite small and fine if you're there a couple days, the kitchen is very basic (needs a coffee pot.)
When we first saw the listing it had one price, by the time we were ready to book it (a couple hours later) it had gone up $9. We booked it and the price showed $15 above original price per night. We asked Ricardo about it and he said airbnb has something called intelligent pricing, adjusting price based on demand. This is not something we appreciated as the demand was US looking at the listing. We hoped he would have honored the original price. We are airbnb hosts as well and will not ever use that option.
Besides that blip Ricardo is a great host and the apt is fine for a short stay in our opinion.
