Beautiful, sunny top-floor apartment in an elevator building near the heart of Berlin's Mitte district. The spacious, airy one-bedroom was augmented by an extra mattress big enough for an additional guest. Bed, facilities, etc. were all great and Olivier was consistently responsive and helpful. Guests are asked to wash sheets and towels on the morning that they leave (this mitigates cleaning fees, which I appreciated), so visitors with early morning flights may want to plan ahead. All in all, a wonderful experience.
