Richie's place was an absolute delight to stay in. The apartment is furnishings are certainly unique, and we had a very enjoyable stay there. The apartment is large and well-furnished, and the bathrooms were surprisingly luxurious. There is a bus line that goes right by the apartment, and U-Bahn, trams, and many restaurants/coffee shops are a 10-15 min walk away.
For business travelers, note that check-in on Sundays can be more complex because the concierge is not available on Sundays (though Richie went out of his way to be accommodating here), and I found the wifi difficult to manage due to limited bandwidth, though I am unsure whether this was a temporary issue or not.
