Sebastian is a great host, very responsive and helpful. He has the apartment very clean and also you can find everything you need for your stay and even more. The bed and sofa are both really comfortable.
Even though is not my first visit to LA, it is the first time that I stayed at Downtown and the place is lovely and well connected, although the neighborhood at night is a bit noisy because of the homeless people in the street, I felt safe but I preferred not to walk around there late at night.
I left my car at the parking lot in the near square and everything was fine (it costs 16 bucks per night).
I really enjoyed my stay and I would definitely recommend it.
