Hi! We are staying at this hotel in London one night, traveling to Rome for three nights and returning to this hotel for three nights. Can we leave a bag in storage while we are in Rome?
Maybe you have to check with the hotel
I do not know, but as accommodating as the concierge is, I would not be surprised if they would.
I didnt try this facility so wont be able to answer you, my apologies
