The process of getting the keys was pretty clear and quickly. We arrived 10 min earlier that the actual check in time and since we could get the keys we thought we could go to the apartment. But the cleaning lady was still there (which is good to know that the apartment is properly cleaned). She asked us to go back in 30min. The apartment is good, very well located, never been so in the centre of London as this time. Loads of restaurants and pubs and Chinatown is just 7min away. Piccadilly Circus about 4min and trabalhar square in 10(or less) all on feet. The only downside was to wait 20min pass our check in time. Totally recommend!
