We didn't meet Antonio, but he gave us clear instructions how to get into the apartment. When we arrived, everything was clean and ready for us. The apartment is spacious and in a great location in central London. The only strange thing was that on the second day we were there, some other guests arrived and had been told they'd booked the same apartment as us, with the same code to get in. The mistake was rectified by a man who lives upstairs, but if we hadn't been there these other guests would have entered our apartment and gotten a shock to see all our things there. Other than that, everything was great and I would highly recommend this place!
