I brought my kids (7.5 and 4.5) and my aunt to Taipei for 7 weeks during the summer, with my husband coming to visit for a week in the middle, and we were all very happy with Nomads' place. The apartment is well-located, comfortable, clean, stylishly decorated, and has great air conditioning. The location of the building is central and safe, very close to the Daan MRT station (about 1 or 2-minute walk) and several bus stops. There are lots of markets, dining options, nightlife activities, post office, banks, 7-11, shops and services -- basically anything you would need -- within a short walk. There is a 24-hour doorman in the building, which is helpful if you need someone to take deliveries of packages, etc.
Nomads and his wife were great hosts, greeting us upon arrival, arranging our airport transportation, bringing over snacks and responding to our questions and requests in a timely manner. They even provided a stroller for me to use for my younger child, which was great when we needed to walk longer distances. I highly recommend Nomads' place to anyone visiting Taipei!
