I'm going to Lisbon for a couple of days, with an elderly relative. Can you recommend sightseeing suitable for her limited mobility (tires easily but can manage steps) and need to be near a toilet / visit places with a loo?
Can't speak specifically about lisbon (sorry!) but I took my dad for a last holiday abroad to Barcelona. In retrospect he was in early/ mid stages of dementia, which is not you r situation, but here are some things that helped: Being liberal with hailing taxis as soon as he got tired. Building visits around things he was into - history, churches, restaurants. I researched restaurants in advance by using the website Chowhound and posting questions/ soliciting recommendations. Avoided very noisy venues (not always easy in Spain!). Lisbon can be hilly when you start going up to the higher neighbourhoods. There are tramways/ funiculars that go up the steep streets- maybe research where the funiculars are in advance. Museums will have loos, and cafes of course. From memory the Gulbenkian museum is very good. I am glad I took him on that hoilday, even though it was exhausting (for me) at times. Good luck.
