This place is exactly as pictured - well designed, decorated, and stocked. Meet up with Catherine went as expected. I printed a picture of the front of the building and printed a walking map (in case I didn't have wi-fi) from the MRT so I found the place with no problems (3 min walk). The neighborhood is a gem. There's a nice quiet park across the street for people watching and a great mix of shops - artists, designers, pottery, Euro-Japanese house wares, every car and scooter part imaginable, and small restaurants and local bars of all varieties to tuck in. Both the Ningxia Night Market and the Taipei Main Station are 10 minutes away by foot making Dom and Catherine's location unbeatable.
Also, having the ability to do laundry was really helpful - just keep in mind you will be air drying your clothes.
