This Airbnb succeeded in the three ways most important for me:

(1) The overall experience was very positive and well worth the amount paid.
(2) The host was pro-active and detailed in providing us information for our stay. They were incredibly responsive during our stay when we had additional questions.
(3) The apartment was clean and cozy, so everything about our time there was about our enjoyment and not about things we might wish were different. From bathroom, to bedroom, to kitchen, to common area, we found everything we might want.

*This last bit isn't to suggest the place doesn't have character; quite the opposite. However, sometimes you know a place is good when you don't notice things, because everything is just right.
