The rabbit hole is small but all you need if you are busy all day exploring L.A. and their surrounding areas anyway. Dean communicates very well and answers any questions right away and also gave some very useful tips and pointers about what to do and where to go. We always felt safe and comfortable there!!
We didn't have the time to explore the are via bikes, but given the location and all the hills, i would recommend to rent a car nonetheless. Via car the rabbit hole was so close to so many places (about 10 - 15 min) - Santa Monica peer, Beverly Hills, many hiking areas, Venice Beach, etc.
The garden with the pool is beautiful and is great for someone who wants to hang out and relax - again, we didn't have the time in our schedule, but the few times we made time to just sit down, were always very zen and relaxing with all its beautiful plants, flowers and bird noises.
I was impressed by how well the bathroom was stocked with shampoo, conditioner, toothpaste, plenty of towels!, lotion, hair dryer, hair straightener, etc etc. It's so great, especially since I forgot to bring some stuff.
You won't be able to prepare elaborate dinner meals, but can easily prepare some breakfast, heat up leftovers from restaurants and make yourself a much needed coffee or tea. There is also a burner plate, so you could heat up some soup or so. Dean also made sure to give us a dedicated area in his fridge.
I highly recommend the rabbit hole and would love to stay there again one day.
