I spent four nights at Tim’s with my parents.
The location was one of the reasons we chose his place - extremely quiet and green all around. Yet the S-Bahn is also not too far away.
The place was sparkling clean when we arrived, and generally everything was as described. Towels, soap, kitchen utensils and appliances etc all there. The only thing that’s not there is a dishwasher, but given our short stay and the fact that we barely used the kitchen that’s alright :)
Communication with Tim was super quick and easy, same as the check-in.
I would definitely recommend staying at Tim’s if you’re looking for a place in the green in Berlin.
