Ulla and her family are great hosts! The studio is bigger than it looks on the photos and very quiet (except some kids' noises in the house). Everything was nice and clean, there was a very handy house manual in German and English and Ulla + her family live right next door to help out if you need anything which you probably won't as there is everything you need in the studio anyways with lots of love for details: There is coffee, tea, cream, sugar, salt, oil & vinegar and even sweets and some can food. As I arrived pretty late there were even some crackers and bananas waiting for me. There is no TV but enough books and comics so that you won't be bored (which you probably will never be in a city like Berlin). Wifi was not the strongest/fastest but okay and I had my own data anyways. I stayed there by myself with my bf visiting and staying over for one night but it would easily fit 4. I would definitely consider staying at Ulla's again for my next trip to Berlin (if for leisure or for business)!
