There are several good things about this place. First, location. While the immediate surroundings aren't the most beautiful, you are a couple of minutes walk from Borough tube, 10 minutes from Borough Market and London Bridge, and walking distance from the City.
Secondly, it is mostly very well set up with modern (and apparently very new) kitchen and bathroom. There's a washing machine and dishwasher, and a big TV. Most of the windows are double glazed with very good soundproofing.
Third, communication with Aneel was very good and polite. I was clear on when and how to check in and out.
Just a couple of weaknesses which I think can easily be fixed and elevate this to a five star place: a few marks on the stairwell and wardrobe doors that need painting, for example, and the window in the one of the downstairs bedrooms is not as soundproof as the ones in the living room, which is a slight issue because the apartment borders a building belonging to one of London's universities and the smaller bedroom backs onto a courtyard within it, and there seem to be people talking by that window or moving bins at all sorts of hours. Bring an eyepatch as that's quite brightly lit too.
But all in all this is a good, convenient place and well-run.
