Is ‘we can help you up two steps’ a workable holiday accommodation plan?

People, dialogue, accommodation and prices are fictional.

‘It's only two steps. We can help,’ Daniel says after the apartment host sends a photograph of the entrance. His sister Leena, who uses a wheelchair, replies: ‘I want to be able to leave before you're awake.’

Four siblings are arranging a reunion weekend. The apartment they like costs £720 and has a shared kitchen where they imagined cooking together. Until the photograph arrived, they had discussed the lift but not the route from the street to it. Leena has not agreed to anyone lifting her or her chair. The host has supplied no measurements or further access details.

Another property's quote is £960. It looks more promising in the photographs, but its entrance and bathroom still need checking against what Leena needs. Daniel says that spending an extra £60 each seems wasteful when all four could use the first apartment together. Leena says the proposed solution makes her dependent on the others every time she comes and goes. She also dislikes being asked to inspect every listing while everyone else chooses restaurants.

How should the siblings divide the checking and the cost? What would count as enough information to book somewhere Leena can actually use, without making her defend the same requirement in every conversation?
