My parents stayed at this quaint little mews house in Marylebone over Christmas. Never having stayed at an airbnb before they were relieved that it didn't feel as if they were staying in someone's private home, more renting an apartment, which suited them much better - even if it may be a bit impersonal. The place was spotless, warm, quiet despite being so central in London and had everything they wanted. Would highly recommend for quests coming to visit London!
