Great communication, easy check in with Gosia's help. The apartment is well situated with vibrant cafes and bars all around and easy walks to get onto Berlin's excellent Public transport system. Small room was suitable for an adult (me) and my son used the sofa bed in the lounge. Two friends used the HUGE bedroom/sitting room . What you see is what you get - an eclectic, artistic apartment. Quiet, clean and with all mod cons including dishwasher and washing machine. 4 adults stayed and we never ran out of hot water. Tina's guide that she sends is the most comprehensive one I have ever seen ! No hesitation on rebooking if and when I come back to Berlin. Thank you Tina and Gosia.
