My husband & 10-year old are taking the Eurostar from Paris to London for four days. I haven't been there for 20+ years so I am really excited to return, I love England, and can't believe it's been so long since I've been there, when I used to go there all the time, it seems. My daughter wants to see the historical monuments and the palaces, and I, of course, want to just walk the streets and savor London. Both Luna Simone and Arran are very positively reviewed on TA, there's a 15 quid difference in price. We'd have a private wc & shower in Luna Simone, but kitchen use at night at Arran House, shared wc and shower -- how to choose between the two?
