What is your Club Carlson status?
Gold

Where did you stay? (Brand, Location, Country)
The Mayfair, Radisson Blu Edvardian, London, UK

Were you (or for multi-stayers are you generally) happy with the hotel/stay?
Yes.

Which room did you book and which upgrade did you receive?
Booked standard king and received same.

Did you receive elite benefits?
Complimentary Room Upgrade - No
Early Check In/Late Check Out - Checked in two hours early and also asked for and received a one hour late check out. Don't think my status played a part though.
In-Room Welcome Gift – A first no, but when I asked they sent a standard gift of water, fruits and a box of very nice chocolate.

How are the rooms?
Very good size for London, large bathroom with both shower and a bathtub with a TV. The bed was very comfortable.

What was good and what was bad?

The breakfast is good.

Good and friendly service.

The spa was bit disappointing, the hot stone massage was good but the common areas where small, and there was no pool or jaguzzi. We even had to wait to get a warm chair before our treatment.

Value for money or Gold Points? Would you return?
Yes. Maybe.
