Mary Ann's apartment was our first stop in Europe, and it was perfect for us. Just a 2-3 minute walk (a couple blocks) away from the West Kensington tube station off the District line, it was easy to navigate to via train and tube even after an overnight flight from the states.
Mary Ann was there to greet us, had many tips for local eateries to try (best risotto I've ever had!), and had left a selection of travel guides, extra plug adapters and even a bottle of wine for us.
This apartment is welcoming and warm with old house charm-- a home away from home. The neighborhood felt extremely safe even if you're a single traveler. It's a quick tube ride from Victoria station, and right around the corner are places for take out, grocery, etc. WiFi worked great, too! Highly recommended.
