There isn't a way to lock or secure the door from the inside. That was a big concern of mine. I've stayed at 11 properties from HomeAway and five from VBRO, across three countries, and this is the first time I have stayed somewhere you can't secure the door from the inside. HomeAway's policy does not state that you need a way to secure the door if it is a secure building but isn't it common sense to be able to secure the door from the inside? Even a chain that you can break through would bring piece of mind, and it would make a noise to alert the occupants.
The owner's defense is that they are secure locks and he has them on his doors as well, and he needs a way to get inside in case of an emergency. I too have them at my home (all of my doors including detached buildings), and I feel very safe with them. However, we still have a way to lock the doors independent of the keypad. Hotels have secure locks, but they have a way to secure the door from the inside.
Even if I did feel safe, I couldn't stay there due to the smell. It smelled like rotten eggs if you got away from the air freshener behind the TV. The further away from the door the more it smelled. The owner said it was somebody cooking in the building, but the odor was in the back rooms (bedroom and bathroom) not near the door/hall.
I didn't stay at the apartment for more than 20 minutes due to the smell. The furniture is beautiful, and it looks comfortable.
I gave it a second star for the nice furniture though I didn't sit on it.
