Great choice; marvelous host. As others have noted, you start with the fact that our host messaged daily to ask how it's going and whether she can help!
Of course, you've seen the photos of 'the view' from the room, but we note that they seem to have been taken with a cell phone whose default focal length makes it all look much smaller than when you're standing there. The real view is much MORE dramatic: as if you can touch the Acropolis. Photophiles will want to use a 'real' camera or zoom in your iPhone to match what you see.
This is a very small space, but 'the view' and location and convenient local eateries (like Ergon on Mitropoleos) offset that.
It's an easy walk to museums/sites, esp the nearby Museum of Cycladic Art, whose second floor is an eclectic gem.
