Barcelona for The Three Generations: a Friday-to-Monday weekend

Forty minutes round the harbour on a boat with benches and step-free boarding from the quay, the cable car overhead for the children.

Dinner at six at the 1836 restaurant under the arcades, which serves all afternoon; a table for ten, paella for the table.

A flat promenade of plane trees and benches between the old market and the basilica, an after-dinner stroll everyone can keep up with.

The cable car up to the castle, gondolas that take wheelchairs and pushchairs, the castle terraces flat and the view the highlight.

A 1929 model village of flat lanes with craftsmen at work, benches in every square and lunch at a terrace inside.

A table at the long tapas room on Rambla de Catalunya, open all day, so dinner at half six is normal and the plates come fast.

The nave is one flat floor of coloured light with benches; book the ten o'clock slot, skip the towers, sit for a while.

Big tables, an all-day kitchen and tapas for every age, a short flat walk from the basilica; arrive before one for the room.

The escalators climb the hill for you, lifts inside, the Romanesque frescoes and a terrace with the whole city for a sit-down.

A flat boulevard with benches by Gaudí, the modernista façades read from the pavement at whatever pace the slowest one sets.

A lift to the roof terrace, an audio guide pitched at each age, and an hour that holds eight-year-olds and eighty-year-olds alike.

Four restaurants under one iron roof, a table for everyone's appetite and a lift from the street, then the Aerobus from Plaça de Catalunya.
