Well, it is a convenient place to stay at. I guess if you are a first timer visiting Taipei, you would be shocked with the moldy spots and dusty surface in just about everything in a lived-in tiny apartment in Taipei city (the kitchen and the bathroom in particular). However, I am used to it, because I am originally from Taipei.
Also, the tatami room is a hiding place for mosquitoes. bring your own mosquito net if she does not provide one. (I had to buy my own) The memory foam provided to sleep in this room is not at all comfortable. My thighs are aching from the hard floor, and I am not skinny with rather fatty thighs. And the neighbor upstairs seems to have a bathroom right above, and when they take a shower at night, the water is really loud through the pipeline, and don't even mention the guy upstairs sings while taking a shower.
The land lady is nice, but she is picky about how you should use very single part of the apartment. And she even kind of demands the tenant to clean his/her own garbage before checking out. And this is the first airbnb apartment I encounter to Not have an iron or an ironing board. It is an inconvenience.
