Maximilian was a great host. You might find his apartment a little bit eccentric but it has everything you need to have a comfortable stay, I personally loved the way it was decorated.

He wasn't in Berlin when we arrived but he managed to leave us the key. Later he came by to say hello and gave us some interesting tips about the city.
Even when we left (about 5 am) we had an issue with the cab we had reserved and he called other for us (again...sorry for waking you up!!)

So, if you want to stay in a modern flat, near a metro station (just 2 1/2 blocks), lots of markets and restaurants and for a good price, don't hesitate!
