I will be travelling to London in May with my parents who are both pensioners. Whilst mum is agile and has no problem walking around, dad gets out of breath quickly and needs frequents rest stops. They ideally want to get a hotel within a mile of Buckingham Palace (which is the area we would like to visit the most) and get a taxi from Euston station. My problem is that the prices for a decent hotel right in the centre are extortionate. I wondered if anybody had any knowledge of people with disabilities (non-wheel chair users) getting around London. I don't want to rely on expensive taxis and would like to know if any of the tube stations have lifts/escalators and which ones to avoid.
Any advice, no matter how small will be greatly appreciated. Thank you.
