Ewan is a fantastic host, especially for solo travelers who want to experience London like a local. The flat is large and comfortable, with free laundry, wine, and meal service (when he’s feeling generous). After a few days, it felt just like a good roommate situation.
I highly recommend getting a travel pass for public transit, instead of pay as you go, since the cost of transfers from bus, national rail, and the underground can be confusing and add up very quickly. Ewan is in Zone 2, so the cheapest travel pass will still work. To see most sites, expect about an hour of public transit each way. Heathrow and Windsor are about 1.5-2 hours away.
Cheers, everyone.
