Keyman's Hotel is recommended in the Lonely Planet Guide, and our choice was based on its location -- walking distance from the airport bus, which stops near the Taipei Train Station and the MRT Taipei Main Station exit 6, Mall exit 3 or MRT station NTU Hospital. Not being familiar with the area or language, it's almost idiot proof selecting this hotel as it's the last stop of the airport bus. From there, a taxi driver told us after the driver called the hotel on his mobile phone to find out where it is. But we were tired and didn't want to find it on our own with luggage, so we hopped in the taxi for a two minute ride. And leaving for the airport is really close, with the bus terminal to the airport adjacent to the Taipei Main Train Station.
The hotel has eight floors with 77-rooms. The lobby has no visitor lobby seating. By the floor map, rooms ending in 09 and 12 seem to be the larger rooms. Our room came with a double and a twin bed, able to accommodate three adults. There were stains on the wall, a mini-fridge, TV, piped canned music available. There's a metal assembly bolted to the floor next to the sofa. This turned out not to be a fire escape but rather a hoist guessing for moving large heavy objects too big for the stairs or elevator. This place had seen better days. The beds are too firm, and I couldn't sleep very comfortably. We saw a smaller room done in Japanese-style.
There are lots of nearby activities available without having to leave the immediate area, and next to the entrance a Nova computer arcade which is the place to buy computer stuff. Lots of local food vendors and even a McDonald's nearby if you prefer that, else there's no need, as the Chinese food is great. This is an excellent central location to be based out of.
