Bibi's place is set in a pretty canyon (well, it's a bit small to be called a canyon probably). The position and height of the tower allows for restful gazing at the creek and canyon. We happened to be there during some pretty big rain events, so the stream was flowing and the landscape was lush.
Other reviewers are correct - this is a small space! But it helps that its divided into a lower and upper rooms with the ladder/outside stairs providing some separation. There is no closet, so be prepared to use your bags to stage your clothes and gear, and travel light.
We got in waaay later than we expected, but Bibi made sure we got in OK and met us at our car with a big umbrella (never had that AirBNB experience before!) We enjoyed the style and design of the place, and it felt restful to be there (which we needed after our somewhat difficult drive through the crazy rains). We didn't really get a chance to cook as we had to leave earlier than we planned. The kitchen is small but can be used to prepare full meals. The back yard is big and full of garden spots and places to relax (I'm not actually sure we had use of the yard, but the rains and cold kept us inside anyway...)
The neighborhood is great - very close to shops and restaurants and the 163 highway. This is one of my favorite areas of San Diego.
I'd definitely stay here again!
