Location: Excellent. It is 3-5min walk to Ximen MRT (Blue Line). There's plenty of food stalls downstairs, with Family Mart and Hi-Life Convenience store nearby. If you want some crowd, go to exit 6 where Ximending is.
Room: You can tell the building is old, only one elevator is working and corridor can be dark but there's a security desk downstairs. Teddy and Ann made good effort for the room decoration. There's even washing machine and a mini fridge. What can be improved is the leaking air-conditioner (drips around your feet) and the entrance gate where I had to wrestle with the lock everytime I open or lock the gate. It's really hard to pull the key out but I've feedback to Teddy and they said they've worked on it. Wifi signal and TV is great! Building is on a quiet street so there's not much noise. Room is considered small, fit for 3 but may be a bit squeezy for 4 people?
Communication and Service: Response is very quick, within a few hours on average. Service is okay. I did want to buy something online but couldn't because I'm not Taiwan resident (can't register without Taiwan ID and Taiwan phone number). Owner merely mention that he/she don't have an account at the website so... it just ended there. I understand they're not obliged to go beyond the mile so I guess service is okay.
Honestly, for the price of staying in Taipei, I'd say this accommodation is worth for value!
