Marks place is a great place to stay and Mark a thoughtful and wonderful host.
The room is well located. Easy ride on the big blue bus from and to the airport. Easy walk to the beach or downtown Santa Monica and easy access to other forms of public transport to access the sights or other parts of the city.
The room was clean, large and with one of the most comfortable beds I have ever slept in. I was able to use the kitchen to make meals which helped me organize my time more effectively and pleasantly.
If the room is available I'd stay when ever I'm in LA.
