STAY HERE!
There is nothing more to say about this apartment. The area is good and near the Hollywood main area, the room was outstanding (clean, fresh, heater and ac, big enough for all our luggage, mirrors, tv, everything), Mary is one, if not THE, greatest human being I've ever encountered (nice, always helpful, taking care of everything, courteous) and you would really miss out on something, if you would stay in any other apartment.
There are multiple bathrooms and the building has about 8-10 rooms. So if one bathroom is being used by another person just use another bathroom. That easy!
Some bathrooms were being repaired while we were there, so they could not be used - Mary wrote to everyone a message and explained the situation, so we had all the information. This was great!
There is also everything you need (shampoo, toilette paper, towels, ...).
If I should point out one thing, that was not perfect - and what comes now is kind of nitpicky - the bathrooms were not that warm. There should be a heater of some sort (like in the rooms), so that the bathroom are warm in the winter (we were there in feb 2019).
However, other than that: everything was beyond great. If we ever visit Hollywood again, we will stay there and Mary and here apartments might even be a reason for us, to travel there again all the way from Austria.
If you are not staying there, you will definitely miss out on something.
