We just stayed and left Florence (Westin Excelsior) using SPG points and got upgraded to a junior suite facing the Arno River. Love that property and location.
This week in Rome at Marriott Grand Flora using travel package. Highly recommend against anyone thinking of staying here. Service poor, shower does not drain, after 3 attempts over 3 days to fix it - each time they reported as fixed, but not. The latest was I am sorry from the front desk but I guess we do not know how to fix it. The check in person emphasized that guests using points are second class. She handed us breakfast vouchers and said because we used points, we could not use it for room service. In the room, the breakfast room service indicated when using a voucher, there would be an additional 10 Euros which we would have no issue paying for. Front desks staff unfriend, roof terrace staff worse. The ground floor has a bar with limited food service. A couple of the staff were great, the rest just stood around. We will just use points to stay at the Westin Excelsior in Rome if we were to return.
