PROs: Great location - a very short walk from the Metro that will basically get you anywhere in Taipei. Portable wifi is also available *for an extra fee*, but it is very useful and works across the whole country (we went out of Taipei for day trips). Hosts are also very responsive if you have questions.
CONs: Unfortunately as AirBnb is illegal in Taipei, the instructions to get to the Airbnb were vague and only led you to the general area (they probably don't want to send the actual address to you before they check that you're not the government), and without internet it was almost impossible to contact the host. HIGHLY RECOMMEND that you make sure you either have access to internet or communicate well in advance the exact location of the building, otherwise you could be waiting close to an hour like we did before they come down and find you.
