The former Highlife Breaks managing director is charged with finding accommodation for Olympic officials, committees, coaches and the 20,000 accredited media that will attend the London Games.
As part of the role Taylor will negotiate additional hotel rooms and rates where needed and make sure existing agreements with providers are delivered.
Taylor will also liaise with tourism bodies VisitBritain and Visit London about their plans for spectator accommodation.
"London has an excellent network with many more rooms available than Sydney and Athens and I look forward to developing this network and providing first class accommodation standards."
Her appointment comes a week after the Government delayed publication of its Olympic tourism plan for a second time until September.
