Just for the record, I booked the room for my son and then Kerem agreed that a friend could stay too. However the accommodation is not big enough for 2 men as they only realized when they arrived late afternoon on a cold wintery Berlin evening. After my sons' friend sought alternative accomodation, Kerem disapproved of my son and told him he couldn't stay there either. I don't know exactly what happened - there are 2 sides to every story - and no doubt you will be able to read Kerems immediate impression of the boys. I ended up paying for 1 weeks accommodation (my apologies...I received 10% refund), 1 weeks accommodation in a hotel and a lot of anguish.....) so the lesson I learnt and probably should have known before: 1) never book a room in someones apartment and 2) don't book 3rd party ie for your son, because Airbnb don't take responsibility for such bookings. Anyway....I can't say anything about the accommodation or the bed....my son was there for a total of 4hrs.
