I stayed at Anthony's place for four weeks this summer during a long visit to my hometown, and it turned out to be a very suitable place for a long-term stay, plenty large enough for one person and self-contained (e.g. there's a washer and dryer in the basement).
As you can tell from the photos, the small house is decorated with many interesting "retro" touches and details from the city and neighborhood (it looks even nicer in person), the kitchen is large, and the living room is comfortable and cozy.
What's not pictured (as I recall) are the covered front porch and open back patio, both with seating and with a table on the patio, which I appreciated despite the Columbus's typical summer humidity, mosquitos, and out-of-nowhere downpours.
One caveat: there is no table inside, and the large kitchen counter is not the type for seating, so plan accordingly if you require a hard surface for eating or working.
The neighborhood is very quiet and calm and predominantly residential -- there's really not much street noise at all, great for peaceful sleeping! -- yet conveniently located near grocery stores, many good restaurants, coffee shops, and bars, and right next door to the beautiful and popular German Village neighborhood. I don't use a car, but had no problems getting everywhere I needed bike or foot (there are also city bus lines that run nearby).
BTW, coffee shop telecommuters will find various options, but I should specifically note that just a few blocks away is a local gluten-free bakery, Bake Me Happy, which also has quite decent coffee, ample seating, and WiFi.
Finally, I'm not sure why "private entrance" is crossed off on the list of amenities; this is a stand-alone home with no wall-to-wall neighbors, on its own private lot. The entrance is private as is the rest of the home. (True, there is the security system voice that will speak to you every time you enter, and -- pro-tip -- make sure you listen when she says to disarm the system NOW, lest you will trigger an alarm and call from the security company folks... at least I can verify the system works.)
