Teddy's place with the help of Ann is overall ok.
I have to highlight that we have quite high standard of accommodation and is the first time we actually use airbnb for ourselves rather than stay in hotels.
We had some check in and communication mishaps but that could be due to our circumstance with us having a very late moreover delayed flight arrival in the wee hours of the morning and a somehow last minute booking within a 24h+ lead time for them to prepare the room and check in details so perhaps by booking with more time in advance and check in within regular hours it would be smoother.
The place is overall clean, with everything you need (Strong Wifi, Fresh towels, soaps and shampoo, ect.. a washing machine with powder even, cooking utensils but I think you won't be needing that) although somehow it could be a little bit better maintained as some wears are starting to show but it is also probably due that it is located in a somehow old building at the heart of Ximending.
Most of Taipei's building are somehow old, if you are familiar with Hong Kong Kowloon's area, think a little bit of the same style.
The Location however is its major advantage and definitely great.
Located within the trendy Ximending shopping area with lots of shops, Banks for currency exchange and eateries nearby until late at night, you won't run out of things to do or eat here.
Less than 5m from Ximen Metro station, you can access anywhere in Taipei very conveniently. 7/11 or Family mart less than 1m downstairs.
Ann afterwards made up for the check in mishaps with good communication and flexibility with trust during our checkout as we were still managing the logistics for our trains to the provinces.
All in all if you do not have too high standard and want a good value for money place to sleep and rest in trendy Ximending as your base to visit Taipei, this will do perfectly.
If you are expecting hotel standards, you will have a look elsewhere and pay the price for it.
