A seamless six month stay for my housemate and I.
I do not think it would be possible to have a better located apartment. There is a LIDL literally across the road. Under 10 minute walk to Ostkreuz (where you can get a number of key S-Bahn lines and regional trains - including the FEX and RE23 which will get you to/from the Airport in less than 20 minutes). Treptower park along the water is less than 10 minutes. Boxhanger Platz with yummy food and Sunday flea markets is 15 minutes away.
Main bedroom is extremely spacious with a king size bed and walk-in wardrobe. As with the living room, with a very comfortable fold out bed (can bed 2 people) and projector screen. The kitchen as well was a perfect size, and was very well equipped (the fan-forced over in particular was great). The bunk-room is understandably a bit smaller, but with a great wardrobe space and an in-looking balcony.
Luciano was so easy to communicate with. We would not have stayed anywhere else
