Overall a decent place to stay in Berlin (BUT PLEASE SEE VERY IMPORTANT NOTE BELOW). The apartment is large and in a great location. It is clean and tidy but as others have commented it is in need of some TLC. Marked walls, significant mold in the bathroom and loose floor tiles in bathroom etc.
The area is quiet for Berlin, but if you have your windows open on a warm summer evening it can be a little noisy from passing cars etc. Saying that you are in a city so that should be expected.
It would also benefit from a fan in each bedroom as with the heat and humidity it can get hot in the summer (just a suggestion for the owner). So overall I was very much OK with the apartment.
One thing I was not happy about was the communication/checkin/potentially hidden fees. I did not get any info by late in the evening the day before I arrived and had to send an email. I did get a quick response with all the info I needed. In that response however was a section asking for 10 euros per person for linen and an additional amount for city taxes (approx 25 euros). So about 55 euros extra in cash to be placed in the owners mail box (both AGAINST Airbnb POLICY). I pointed out that in response to previous reviews commenting on this the owner had stated that these costs were included in the price after 2015. If so why was it in the checkin instructions. I noted that more recent reviews (EVEN LAST MONTH) had mentioned having to pay this additional cost. I do feel that the owner is just trying to see if they can get extra money from those that don’t question. It shouldn’t take 4 years to change your email checkin instructions.
To be clear when I politely raised this in a second email where I cited previous reviewers comments I immediately got the short response "Yes it is included". So there was no extended discussion on the matter. However it just left a bad taste in my mouth. This is the first time I have ever had this come up in all my years of going through Airbnb. Surely bed linens are a basic when renting an apartment/room not an added extravagance.
