This hotel is a great place to visit during a trip to LA, has a great rooftop vibe. It's conveniently located walking distance to the Hollywood stars and other attractions. The rooms are cool, the lobby is practical but with two different chilling areas. The rooms are not bad for the price.
Since LA is a driving city you'll need to have a car, so factor in that you'll be paying to don't valet charges as well. Also a few minor set backs happened during our stay, power and wifi went out for a day and had to be downgraded because of plumbing issues.
Overall the hotel is not bad, and if they do a full renovation in the near future will be a great place to stay. It's half the price of 5-star hotels with similar theme and crowd, so you do get what you pay for.
In summary, if you prefer quality go for one of the better known 5-star hotels. If you're on a limited budget but want somewhere clean with decent sized rooms and a cool vibe, then Mama Shelter is for you.
