Kate's apartment was perfect for us as it was close enough to the city centre and public transportation, and quite enough that we could get a good night sleep. The communication with Kate was easy, and her staff member met us and could give us local recommendations. A big pluss for the piano (and Kate`s nice staff member who enjoyed a little Coldplay sing-a-long).
Keep in mind that the apartment is at the 4th floor, and that you have to walk very steep stairs to get to the top.
