Sebastian was really easy to deal with. He was proactive about finding out when we would arrive and flexible on the check-in time, which we really appreciated. The flat's location is amazingly convenient and we arrived and it was clean and well stocked with towels etc. Our only concern before arriving was, based on some other reviews, was that it would be a bit noisy. We were pleasantly surprised how quiet it was given the location and slept really well. We were impressed with the overall experience and would definitely return.
