Yes- I did back in October of 2022 though---I was disappointed- very expensive but not the variety or robust taste that I was expecting. Their breakfast buffet is excellent however the dinner was a let down honestly. The view is spectacular but perhaps gets leaned on in terms of overall review and taste. there is a little informal place called Deli much higher up the stairs that has wonderful food and a passionate staff-- they also have an olive oil store there and you can get some olive oil tastings---better and without the attitude.

There is valet parking in the hotel

The walk is not far but the concierge was fantastic and will take care of everything. enjoy.

Yes re the taxi, but there are lots of steps to the various terraces and cobbled uneven paths/roads inside the hotel grounds too. The rooms are the old houses on the medieval streets and ours had a steep marble staircase to the upper floor (bathroom downstairs and bedroom uostairs). They have some specially adapted rooms though. It is a fabulous hotel (the best I have ever stayed jn) but with mobility issues you may not get the full benefits. i hope this helps.
