The best of all: August was very friendly in communication, met us readily in person despite our very late arrival, cleaned the apartment very well before us and even bought some stuff for breakfast (a special service for long-term guests, he said).
The place is situated in a quiet area with supermarkets, banks, and bus and underground stops pretty near. We found the apartment cosy, even with some style, and big enough for three guests. What wasn't that good was the tiny bathroom the size of a larger shower cabin, but any other apartment for this price had the same feature.
Is definitely to recommend!
