You can go on a special tour on selected days, which takes you into the haunted cellar, underneath the cafe. It's £4 or free to members, and you are best ringing in advance to check when it's running. There's also an attic tour on selected days.

Adults £8.10, children half that. But NT members get in free.

Yes

Frank green was original owner and appears to have been behind a lot of the furniture and room design. I think he came from ' new money ' wealth & an industrial background and to raise his profile invited the then Prince Of Wales to the house. The house itself is very interesting and the haunted room is definitely worth a visit .

You can purchase on line. I highly recommend if you are going to visit several attractions getting the one day York city pass from the visit York tourism shop by the Minster. Will save you money. Only good for the day.

Sorry for the slow reply. I think they did. Can't remember. I have one from the kitchen so probably!

No lift, but a couple of rooms are on the ground floor. Cafe & toilets down stairs. Electronic tablet with images of upstairs rooms available to look at from reception.
