If you have any questions, Nikolai communicated very well and quickly. Check in was smooth. His apartment is located on a busy street which makes it easy to ride transportation to and from sights easily which was important to us. Street noise may be a concern but was not when windows were closed for us. My husband enjoyed running in the morning in the neighborhood and I enjoyed learning how to make coffee in Nikolai’s coffee machine. A super nice kiosk is just outside his building door with wonderful coffee and food. Enjoy!
