The two clear half door/walls as mentioned by Marina is untrue, it is an internal frosted sliding doors that are featured in the newly built modern apartment these days.
In terms of cleanliness, Marina left a private cleanliness feedback to Airbnb suggested that my space could be cleaner in the areas i.e. dust, floors, carpet, towels and linens. There's no carpet in the apartment except guest's room and my room - this is Airbnb not a hotel (don't expect a day-to-day housekeeping service), furthermore I've no rights to access the guest room when the room is reserved; Marina got the towels by herself from the drying rack which were washed thoroughly and linens were changed upon her arrivals. The apartment is getting cleaned every Monday, there was no issues with my previous guests, therefore her statement left a lot to be questioned.
On a personal note to Marina, if you want to save costs - Airbnb might not be a right place for you. When you book the room, you would definitely expect to live with the host, attempt to adapt to the living environments, respect each other, and there has to be give and take on both sides. There is no need for me to arrange my hours, given the fact that i did not interrupt your daily life and it was not necessary for me to have a similar hours with yours. Also, on the first day of your stay, i have made it very clear - open up the new shampoo/ body wash when the previous bottle is being used up, however it was not the case. Additionally, you moved my stuffs without asking at first. I did not leave a bad review as i was not trying to be harsh, but i gotta have my fair share by leaving a public response.
