First off the apartment is in an excellent location. Just steps from the dongmen station. The area has a lot going on within walking distance as well.
The apartment was very clean and well equipped to make sure you are comfortable.
Only slight inconvenience was always needing the help from the front desk attendant to allow you to access the elevator to go upstairs. Sometimes they were away from the desk so you'd have to wait a moment or talk to them to allow you up. They were very nice and just taking a break outside usually so this wasn't too much of a problem.
Overall I would very much recommend staying here for a great experience in Taipei. I definitely want to come back again.
