Sebastian’s place was perfectly located for our needs. Very short walk to Ostkreuz station where from you can easily reach the whole Berlin city as well as BER airport.
The apartment itself has a potential to be one of the most coolest Airbnb place I’ve been but unfortunately it was not well cleaned. A perfect kitchen for fun cooking would for us mean there would also be a stove but otherwise a nice sortiment of kitchen equipments and other electrical devices were available. I don’t know for which use is the nice big TV screen for but we couldn’t watch any of the channels. Also the remote control had empty batteries. Soundproof windows… I don’t know about that but the neighbourhood was quiet and we had a very good sleep in a super soft bed with comfy pillows and blankets. Overall - all good and i'd still choose to come again.
