Awesome awesome awesome location! So much good food available right downstairs during all times of the day and night (beef noodles, pork rice, sandwiches/burgers, wraps, mixed rice, 24hr convenience stores, ice cream, and more!). And if you take the shortcut through the backlanes through the back door of the place, you can walk to the Red House and the heart of the Ximen night market in 3 to 5 minutes, where there's even more food and a whole lot of shopping.
Public transportation is super convenient with two trainlines accessible at the Ximen train station (3min walk through the backlanes shortcut). From Ximen station you're only 1 or 2 stops from other line interchange stations, including Taipei Main Station (which you can then get on to the Airport Train, High Speed Train, and TRA trains, in order to travel to other parts of Taiwan). Taxis and Ubers are also operating in the area 24 hours a day.
The unit itself has no view and the window faces the wall of the adjacent building, but you wouldn't stay in Ximen for the view anyway. Also found some stray hairs and dust around the bed when we arrived, but 10 minutes of cleaning up took care of it so it wasn't a big deal.
The downstairs bed is a bit hard, and the upstairs bed a bit soft, so hopefully your family is like ours where someone prefers hard beds and someone prefers soft beds.
Gave the host feedback about some issues with the air-conditioner and bathroom sink, and they took action to remedy it. Common problem we found here and in all the Taiwanese AirBnB and hostels we stayed in is lack of places to hang clothes and towels in the bathroom, especially when it's supposed to be sufficient for four people. Overall, I can imagine the space being challenging for 4 adults to maneuver, but for us being 2 adults and 2 kids below 12, we were able to find a way to make it work. We only had 1 big luggage bag and 1 small luggage bag, and made use of the many cupboards and drawers in the place to make the space more comfortable to move around in.
The coin-operated washing machine and dryer on the same floor as the unit was helpful as we were staying in Taiwan for a long time. Our host was also flexible with our late check-in and early check-out times. Overall, we are very happy with the stay!
