My husband and I stayed at this rental for a month in 2022 on a work trip. Overall we felt there were some strong pros and a few cons.
Pros: Location! Well-situated in West Hollywood, but on a quiet residential street so not much noise in the evenings. Parking: Ken kindly provided a guest parking pass for street parking, and we rarely had any issue finding a spot to park. The apartment itself is a good size, and the internet is fast enough to work remotely and take video calls.
Cons: this rental feels a bit unconsidered. For example: when we arrived, there was a cutting board, but no knives; coffee maker, but no filters; etc. There are dishes and a few cooking tools, but it's not really a kitchen well-equipped enough to actually cook in. We ended up purchasing about $100-$150 worth of stuff to help supplement a bit, and left those things there, so perhaps it's less of an issue going forward. There is a shared patio with the front house (Ken's) and another rental unit below which had some random construction-type materials strewn about for the duration of our stay - used paint rollers, medium-sized pieces of what looked like drywall, etc. There are window a/cs in the rooms, but they don't work super well which I imagine would be more of a concern in the summer months (we had a couple of abnormally hot days). There is a driveway for the front house, but you can't use it to load your things in or out, which is a bit of a slog with a month's worth of suitcases from the street while squeezing around the front house's car.
Overall I would say that this is a rental best suited to a short stay, but wouldn't recommend it for a longer-term visit.
