Our stay in Room 17 was overall a positive one. The room is in a great location: just off Hollywood and Vine; walking distance to great restaurants, bars, and shops; seconds to the Walk of Fame, and a short walk to the Chinese Theatre; and only a ten-ish minute drive to Universal Studios. It is also located close to major bus routes that can get you to and from Santa Monica, the Sunset Strip, and other locations. The location was important for us, it helped us tick many things off our L.A. travel list.
The room itself was clean, tidy and welcoming. Mary even added an extra futon bed for us, which we appreciated. The bathrooms and kitchen were also very clean.
The only issues we encountered were outside of Mary's control. The rooftop bar next door and the bar across the street were noisy until early hours of the morning, and the street cleaning and rubbish collection at dawn both made sleep difficult. We were largely unaware of this from her listing, but as I said, these are outside fo her control. The lack of air-conditioning also hampered sleep, as the days and nights remained very warm. We're from Australia so are rather used to this, but it may be difficult for others to handle. Mary did provide fans and ear-plugs though, so she did attempt to help with these matters. She has since bought air-conditioners too, so this may reduce the heat issue.
As a host, Mary is a very good one: she responded to emails quickly and with detail; gave us thorough information about check-in, attaining the keys, and check out; allowed us to store our luggage for the day after check out (thank you!); and was very friendly in our brief meeting. Overall a good experience, thank you Mary!
