When we arrived to Berlin, we told our host we had some delay on our flight and she told us she wouldn't be in the apartment after 2pm even if we could have only access the appartnent as of 1pm based on the current conditions she has.
When we arrived to the appartnent we found out a very messy apartment with a very strong smell everywhere around and some small flying insects particularly in the kitchen/toilet area and we found out later that also in our room.
We were asked if we brought towels to shower to what we replied that we did but didn't know that we wouldn't have a hand towel either... So basically we were left with no towels whatsoever apart from our owned. Also we found out we were expect to bring the gel, shampoo too because there was really not much there useable.
We found out when we were in the room that there was no way to lock it, this, we didn't mind but after finding out that the appartnent was (even if we locked it before going to bed) unlocked always in the mornings we really felt unsafe.
Cleanliness in generall it was very bad. Not only the apartment in general was messy and with a very strong smell all the time, but also the toilet and bathroom in particular was very dirty and full of hairs everywhere. Also the lack of hand towels or a second toilet paper roll was very disappointing.
