Nikolai's place in Vienna was excellent. I highly recommend. The location was very convenient and easy. Since the booking in, the communication with Nikolai was quick and helpful. The apartment itself was clean, organised and very charming. We had everything we needed and more. Nikolai was very kind to provide a list of cafes and restaurants nearby. Also, he allowed us to check out later in the afternoon since our flight was only at 20:20. This way we could enjoy another day in Vienna without worrying about our luggage. Overall, we had a wonderful time in Vienna staying at Nikolai's apartment. I would love to stay there again.
