Sara's place was just perfect for our group of three adults. Would be comfortable for four also. Check-in was smooth and super-efficient. We let them know when we'd be arriving and were greeted at the flat on time. The flat was beautiful with everything you'd need for a lovely London stay. The neighborhood is great....close to Hyde Park, Portobello Market, convenient tube stop, cafes, restaurants, yet very quiet and felt very safe. Beds were super comfortable, bathrooms great, kitchen lovely. Everything super clean. Close enough, yet far enough away from the city center to feel very relaxing. The huge windows and leafy trees outside made the flat a very peaceful place to relax after a day of sightseeing. And it's a quick cab ride to Paddington and Heathrow Express, if that's important to you. Yep, there are lots of stairs, if that's an issue for you, but our group of 60+ folks (one with a bad knee) managed fine. Would definitely stay here again!
