A small cosy flat that faces the calm backyard - so there are no street noises. There's everything one could need for a stay in Berlin: the kitchen is well-equipped to cook your own food, a very good shower (the head of water is strong as hell! :D) and a washing machine. My only point of critique was that there were no toilet paper and soap in the bathroom, so we had to buy it first - but that's a nitpicking.
We liked the surroundings - calm but only a stone's throw away from the city life (Schönhauser Allee and Mauerpark which is worth visiting on Sunday they say, and a vegan cafè in Veganz supermarket where you get really good food and awesome smoothies).
Michele is a very nice and friendly host, we had a lovely chat the day we moved in. All the questions we had before our visit he answered very fast. It was a pleasure to deal with him. more
