Renting a scooter for disabled in St Petersburg Russia

See if any of these links lead you to answers to that question: accessible travel linksunder Accessible Travel

As far as I can remember, the Hermitage is not very disability accessible. There may be elevators, but I recall many staircases, and the main walkway to the entrance was largely gravel.

Most of the Peter and Paul fortress is on one level (with the exception of the walls and the city museum), but once again, the grounds largely consist of uneven gravel.

This is the only thing the Hermitage's website say on the matter:
"For visitors with limited mobility
Entrance from Palace Square. For all questions about arranging visits to the museum for invalids and rental of wheelchairs, please contact the administrator in the Main Vestibule or phone: (812) 710-90-79."---------------------
I think the Russia Museum is better suited for scooters, this from its website:
"FOR DISABLED VISITORS

You can lease wheelchairs free of charge at the museum.

I was very underwhelmed by the P&P Fortress, I would use that time to tour St Isaac's Cathedral instead.

To all three people who answered my original post, thank you for very helpful advice.
