I booked this apartment for my mum as she was visiting me in Berlin. As she has mobility issues, she was happy to find a place on the ground floor and do close to the train station. Sam was very helpful and quick to respond to questions prior to her stay and to let us know how to access the keys upon arrival /departure.
The flat had everything necessary for a self-catering stay, including cooking basics such as oil, salt and some spices.
For people with mobility issues travelling solo: the cupboards are extremely high! There is a step-stool to aid access but my mum wouldn't have been able to reach the cutler /crockery without my help and even I had to stand on my tip-toes on top of the stool.
Minus points for cleanliness: I think someone probably vacuumed and wiped down the counters before our arrival but it didn't seem as if the flat had been professionally cleaned. The cleaning fee seems unreasonable considering this. There were water marks on the floor and noticeable dust in the corners of the rooms/windows. The major cleanliness issue, however, was that the dishwasher was filled with dirty dishes and there were no dishwasher tabs so we had to clean up someone else's mess per hand.
I did raise the issue through AirBnB but didn't get a response. Sam was responsive in all other regards prior to our arrival - perhaps there was an internal glitch that prevented this issue from being resolved?
