Allen's place is just like the pictures. It's comfortable, very clean and has a number of amenities. Nice shower as well.
Allen met us and showed us in to the property. He was polite and funny and spoke good English. We were tired after an early morning flight so probably seemed quite miserable to him but he was very upbeat and energetic. The property is 5 to 6 minutes walk from the MRT station and there is a 7-11 right outside along with some slightly bigger convenience stores.
But where Allen really went above and beyond was actually after we left. I forgot my wedding rings as I put them in a drawer in the apartment and left without them. Allen recovered them for me and sent them by Fed-Ex to my home in England. We paid for the delivery charges but he sorted everything out and asked for no money. Thank you so much, Allen.
Overall, I can highly recommend a stay at Allen's place if you visit Taipei. The city itself is fantastic as well.
