The apartment and location are accurately described. Its a first floor residence (great for stroller access) with a full kitchen and washer. The bedrooms were clean and easily sleeps 7 - 8 adults. Towels were provided and plenty of handy napkins. There's only 1 bathroom, so plan mornings accordingly. The hot water is a little quirky, but works when you get the hang of it... don't get me wrong, its not the old-style manual hot water furnace. Its modern and automatic, but needs a bit of getting familiar to get the hot water running... one or two showers should do it.
The apartment is two streets away from the Tonghua night market... which is also busy in the morning with vendors and food. Its a great place to pick up snacks, which easily turn into a inexpensive dinner or lunch. For breakfast, there's a lot to eat along the market in the morning, but we frequented the soy milk / breakfast shop at the end of the market (on the right side corner) and the wonton noodle place two stores down.
The MRT (subway) is a close 5-10 min walk through the market. While we didn't try walking with luggage, the route is easily navigated (backpack, and a roll aboard). The closest exits have escalators and stairs. The elevator is on the other side of the main street.
Taipei 101 is close, but we chose to take a taxi (~$85NT).
As a bonus we found the numerous pet stores a nice diversion for my 18mo old daughter. She loved walking buy and watching the kittens and puppies... on the way to the 7-Eleven.
This would have been a "5 star" rating if it wasn't for a mishap with the bedroom door. If its not fixed, use a piece of tape to ensure the latch doesn't fall close and lock the room with no access to the luggage or handbags/personals. Door can be "jimmy-ed" by lifting the bottom corner... if it doesn happen. We used tape to prevent further mishaps.
Overall we really enjoyed our stay. It really allowed us to feel like "locals". Great for families with kids.
