I enjoyed my stay of a little over a month at Esther's rooftop apartment. It's a short walk to the blue metro line, and there's a UBike spot right next door. There's a small night market very close by with lots of options for lunch and dinner, and plenty of convenience stores and a supermarket as well. I particularly recommend a coffee shop nearby called 烘焙者咖啡(松德店), if you like siphon coffee. The Taipei 101 area is a 15-20 minute walk, and in the other direction there are some nice hiking areas.
The apartment is well decorated, although the desk chair is a bit uncomfortable. The bed and bathroom are quite good, and the AC worked well enough. Overall, it's more geared towards shorter stays due to the size and lack of cooking facilities. It's on the 5th floor (depending on how you count it) with no elevator, which I don't mind at all, but might not be desirable for some people.
There was no issue with checking in or checking out, and the instructions for finding the place were good.
