My girlfriend and I stayed at Tanka and Shibanee's place for two weeks, and they were fantastic hosts -- friendly, kind, and extremely hospitable. We were able to try some excellent Nepalese food, and they were extremely helpful whenever we had a question or issue. Tanka and Shibanee are definitely the best of the best of Airbnb hosts.
The room is larger than it appears in the photos, and the whole house is very clean and well-kept. The neighborhood is quiet and pleasant, with easy access to public transport.
I would definitely recommend Tanka and Shibanee's place, and hope to stay with them again in the future.
