I stayed at Dima's place for one month and I have to say everything went really smoothly. Dima is amazing at hosting and really cares that you have a good stay. The apartment was sparking clean, fast internet and good work setup. The location is great: right next to a big park, and very close to restaurants, bars, shops, and the U5 metro line that takes you to lots of cool spots around Berlin. I'd recommend that apartment for sure! Thanks Dima!
