Rosie is a super host who communicated brilliantly and gave us plenty of really helpful local tips. She even organised extremely good value Airport transfers for us, which worked seamlessly in both directions. Both drivers were very courteous and it took the stress out of us otherwise having had to arrange travel with an unfamiliar minicab firm. The apartment is outstanding and very comfortable, equipped with everything you could need for a relaxed and enjoyable stay. I'd say it's actually more spacious than it looks in the photographs! The beds were super-comfy and having the option of bath or (huge) shower was a real bonus. The location, right in the heart of Mayfair, couldn't be more perfect for a pleasurable break. This is an absolutely fantastic alternative to (pricey) Mayfair hotels and we'd thoroughly recommend it.
