Self-contained flat underneath the main house where the owners live. The private entrance unlocks with a numerical keypad. We liked not having to carry keys around. Beautiful bathroom with large bathtub although the hot water ran out before the bathtub was full. The flat had a strange smell on the first day, but it seemed to go away over time (or we got used to it). Apart from that, it was lovely as a base for a couple of days. The record player and records were a nice touch. A microwave would have been nice (but was not expected). As other reviews have mentioned, there is noise from the top floor and neighbors, but we were ok with that. The area is residential. There are restaurants and cafes and a Bart station around 9min walk away, but you have to walk through a dodgy and smelly underpass to get there.
