Mary's flat or small hostel was really perfect. It's location is next to Hollywood boulevard and the metro station Hollywood & Vine, which was great to get around LA fast. As indicated, it gets loud during the night, but we slept great with earplugs. The neighborhood is okay, a bit loud and sometimes sketchy, but it comes with Hollywood. We did feel safe though.
The flat was nice and very clean. It is cleaned daily by Mary and kept tidy and neat. We had 2 bathrooms on our floor, which was perfect. Our room was big and even had a couch and a small fridge in it. We would definitely recommend it, especially for it's location!
