Tia's place is fantastic! Located in a quiet residential area, but very conveniently located, with a short walk to many great restaurants, shops, bars, train/subway stations, etc. in the Shinjuku area.
Tia was incredibly helpful, very hospitable, and very responsive to messages. Tia met us at her place, walked us through a lot of great information about the area, how to navigate Tokyo using the trains/subways, suggested things to do, and places to eat. All very appreciated, particularly as this was our first time in Tokyo.
Tia's place was very nice, spacious, very clean, and well equipped. It was filled with many extra amenities/ little touches for travelers (such as 2 pocket wifi devices you could take with you as you explored the city, guide books, access to bicycles, etc). It was great to have 2 separate bedrooms, and you could transform the living room into a 3rd bedroom if needed (using a futon as a bed).
Tia is the most helpful Airbnb host I have ever had, and my 2 other traveling companions say the same. Overall, it was a great experience, and I would highly recommend Tia's place!
