Overall, we had a great stay in Charlie's apartment.
We arrived late and also left late, late checkin/checkout was easily arranged with them. Charlie helped us book for airport transfers and Laurence was on-time at the airport and in picking us up from the apartment for departure. Charlie and his wife Tina were waiting for us at the apartment when we arrived.
Apartment is cozy, we were 4 adults and 1 toddler, and space was manageable. This place could fit up to 5 adults, as the sofa can also be used as sleeping space, that is, if you're ok with only 1 toilet&bath (some would just have to wake up earlier than the others). Husband was happy with the TV as it had good selection of sports channels (though commentators are dubbed in Chinese).
At first we had an issue with the wifi. On our 2nd day, we figured out that the password given had a small error. It should have been small "h" instead of capital "H".
The place is generally clean, except that the beddings and towels didn't smell fresh. They must have been stored in the closet for a while. Also, what's supposed to be the kitchen of the unit is now used mainly as storage area. I wish they would organize it better so that it won't look so cluttered. There were also stuff under the bed of the master bedroom.
There's refrigerator, microwave and electric kettle. But there were no spoons/forks/plates. We had our breakfasts in the apartment so we bought disposable utensils.
We were able to use the closet in the master bedroom, and the drawers in the other room (the closet there had stuff in it). They had hangers, too, which was great.
Remote control for AC in the master bedroom had leaking battery. Fortunately, it's the same AC model as the one in the living room so we just used that remote.
The best part of our stay is the apartment's location. It is along a major road, with lots of stores/restaurants in the vicinity (my toddler was really happy with the Hello Kitty store just beside the apartment entrance). Transportation is ok - there are a lot of taxis passing by, and address is quite easy for the drivers to find (we usually just show location via Google map). Sun-Yat-Sen Memorial Hall Station is just a short walk away. We walked from the apartment to Sun-Yat-Sen Memorial Hall complex, then eventually walked onward to Taipei 101. Apartment to Taipei 101 is just a short taxi ride away if you don't want to walk.
We might consider staying here again in one of our future trips back to Taipei.
