Simon responded very quickly and the flat was clean plus very central. Due to flight cancellation Simon even returned money to us although short notice. But we travelled with a child and didn't know that long street (very close to the flat) is so noisy during the night. So we didn't have any sleep during the night and left the next day. Maybe that's different during the week...
Overall good flat for party animals, not a good choice for people who need a good night of sleep.
