Tulika is the best host that I've ever had on AirBnb.
She is extremely responsive to messages and flexible with regard to the apartment. Whenever I had a question, she responded within minutes and properly set expectations for entering and leaving the apartment.
The apartment itself is well located, clean, and comfortable. It has all the amenities that one would need and the building is well secured. The heating in the building is controlled centrally and when it turns on at around 6 AM, the vents in the apartment make a fair amount of noise for 5-10 minutes. For light sleepers, this might be an issue. Since the heating is controlled by the building, this is out of Tulika's control.
The neighborhood around the apartment is comfortable and there are plenty of bars and restaurants within walking distance. This apartment is great.
