You get such a good value for money at this place, and Marc and Kelsang are so nice and friendly. They are tour guides so suggested some really good places to go, as well as some places to get to see a bit more of the 'real' berlin. The apartment itself is in a really good location, it's 10 mins from two different stations and close to some really cool bars and clubs, it's also only a 20 min walk from east side gallery! The area feels super safe even at 5am in the morning coming back from Tresor (a really cool club 10 mins away). Would definitely stay with them again!
