Beautiful bright apartment (bring eyeshades, no way to darken) ; very efficient host; lovely street -- a very pleasant walk to Harvard, etc., if weather is nice.
All three bedrooms are flexible -- no standard "beds," two convertible sofas, one kinda giant futon with a lower futon that can pull out from underneath.
Three TVs but I couldn't get any of them to work (I had hoped I could just power on and change channels and volume; they needed network settings and various other things that, with two Harvard degrees but no millennial skills, I couldn't handle). I also couldn't get any of the three available wifi connections to work -- the passwords were easy, but in each case rejected. May simply have needed to re-set the router, but I didn't have time or energy to fuss with that, or to call the host for help -- which I'm sure would have been forthcoming.)
Because it was Harvard commencement week, there was an unbreakable 4-day minimum and a (I thought) very high price. But look: I would have done the same had I been the host: supply and demand.
