Alex and Rafael are wonderful hosts. The check in procedures are really clear, just make sure that you read the check in procedures prior to your arrival (the entrance is indeed very hidden).
The location is perfect if you plan to explore Universal and Hollywood/Berkeley Hills area, driving distances are roughly 10 mins. My friend and I stayed for three nights and the neighbors are safe. Parking is really easy as well (street parking). Everything else are described as is in the profile/pictures. I'd highly recommend this place and will absolutely come back again.
