Where should DM stay in London?

[MNDaughter]

DM, widowed, wants to spend 10 days in London. She knows some people, but mostly wants to go to museums, shop, walk, maybe go to a play or a concert.
She is talking about staying at a serviced apartment. It looks nice, and it's in a pleasant neighbourhood. She says she doesn't want to eat alone in a restaurant and wants to be on her own schedule for breakfast.
I think she should stay in a certain small, cosy hotel. Breakfast is optional. There is a restaurant/bar and they do an afternoon tea. She won't have to buy groceries or load/unload the dishwasher all on her own, just as she does at home. I think a serviced flat hotel will have more families, so there will be fewer guests like herself.
The apartment costs more, so the savings of home cooking doesn't really apply.
What do MNers think?

I think 10 nights eating out alone would be a bit rubbish, the serviced apartment sounds like a great idea.

If she’s in Central London it won’t have to be ready meals, she can get all sorts delivered or buy take out from Ottolenghi and similar.
