Kitty is lovely and very professional about having guests stay at her place.
She had everything prepared for us - fresh bed, keys, towels and even maps and guides of the city.
The flat itself was nice and clean. However looking at the pictures we had expected something truly amazing and were a tiny bit disappointed with the overall condition of the flat. Especially one night (we stayed in January) it was quite stormy outside and the draft in the flat was very uncomfortable. The noise outside on the street, as mentioned by previous comments, wasn't a problem at all.
All in all we were happy and would definitely recommend staying with Kitty.
