It's a lovely apartment in excellent condition, but it's small. My brother and I need 2 beds when we travel and there was minimal space. We had to keep our suitcases in the entryway (along with their canister vacuum). For a couple sharing the bedroom it'd be workable and cozy, but not if you need 2 beds.
There is easy, free street parking and a bus stop within 100 feet that goes to the train station and on to York Minster. A bus day pass is 4.60 pounds which is hardly more than 2 one-way tickets (2.20 each).
