Next time I come to Berlin, I will :
1. Book Robert's room
2. Ask him to join for a beer
And well, if the room isn't available, i'll just go straight to step 2 and have a beer with this andsome guy !
A flat with a great location (nearby the subway station), clean & quiet. Concerning Robert, a very respectful person, generous & openminded. As a young woman travelling on her own, I highly recommend !
