 I wanted to book regularly and when I called to arrange this the reservations person was not at all helpful and lost 40 nights 
 My room was really comfortable I was upgraded on the day from the room type due to availability of a Superior Standard I heard the bells of St Pauls twice in the evening and once in the morning which is not bad given that they ring every quarter of an hour 24 hours a day This may differ if you are in a different place in the building
