My in-laws from Spain have stayed at Max and Susan's place for 1 month (March 2016). We were looking for a quiet, comfortable place close to our house. The description online seemed to fit what we wanted and the reviews were good. However, the guesthouse is even better than what we expected, and all our family would qualify the overall experience with 6 stars if we could.
According to my in-laws (retired, close to their 70's), the place is surprisingly quiet considering it is close to a few busy streets. The location is terrific for a short stay in LA. The guesthouse is a separate, stand-alone room. Privacy is almost complete. We found the place in outstanding conditions, clean and very well equipped. VERY comfortable bed, small but functional bathroom, kitchen and rest area (nice tv set and good wi-fi signal). Temperature inside was always good, my in-laws didn't need to use the ceiling fan or heater at all. Plenty of room and furniture for clothes and stuff. Clean linens and soft and fluffy towels every week. You can park one car just at the entrance of the driveway that takes you to the room.
In short, convenient, well-equipped, clean and private studio at the heart of LA.
Finally, It was great to meet Susan, the owner. She made their stay a terrific experience. She was kind, welcoming and patient (considering my in-laws can't speak English), and communicated with them and myself during their whole stay to make sure they were ok, and double check on whatever they could need.
You know how they say "we will be back". And we will indeed, as we have more family coming next month for a couple of weeks, and we have already booked the place again. Thanks Susan, see you again in a few weeks!
