We rented a LandRover for pickup at Heathrow from Dollar Thrifty Rental agency which is housed in the Sheraton Heathrow Hotel. Upon returning to London from our holiday in rural England, we wanted things as easy as possible for drop off of the vehicle and transport to the airport the next morning - so we chose to stay at the Sheraton.
Even though we arrived several hours prior to check-in, the hotel checked us in no problem. (I had looked high and low to find a room at the Sheraton Heathrow at any price....the only booking I could find was through SKOOSH - even the hotel's website had no vacancies for our required night). They stored my husband's racing bicycle (for the UK Ironman race). The Concierge made arrangements for an oversized van to take us to the airport the next morning. Overall, the staff was very helpful and accomodating.
Note: The minibar automatically charges for items that are moved from their spot.....I'd moved some items out to place my personal bottle of wine in the fridge - the next morning there were 60 pounds of charges on my bill. The hotel corrected the charge with no hassle once I explained what had happened.
The bed and pillows were so comfortable, lots of amenities in the room - primarily aimed at business travelers. The view from our room was of the cooling units and roof area - but what can I expect in getting the last room in the hotel!!Excellent bar near the lobby with a fun bartender handling the service.
Highly recommended if you don't mind paying a little extra for nice amenities and being so near the airport.
