This is a good news and not so good news story. On the good news side, the location is magnificent (close to town hall, opera, or symphony houses) with a small, simple, very-clean room for a quite reasonable price.
Not so good news: the check-in experience required a phone call to the owner to get the names straight (likely she'll fix this soon) even with the printed reservation; the room has no air-conditioning and we encountered a very hot week so the room was quite stuffy; largest problem was the listing said rooms were for 2 or 4 people. What this means is that there are two different size rooms: one for just 2 people (small) or another room that can sleep 4 people which I didn't see.
