Chris's flat is very comfortable - light and airy, has air-conditioning though I can't imagine you'd need it; it was quite warm during our stay but the flat never got too hot. Kitchen has everything you need, and there are guidebooks and leaflets around.
The location is also perfect - you can walk to everything, but if you are feeling lazy or tired, it is very close to the U-bahn and other transit. Plus it's right by the market, which is delicious. This is a great apartment in a very nice location.
