Stayed here with a big family group for about 10 days. It really is a great place to stay for large groups — lots of bathrooms, different living room areas to hang out in, and the place was nicely decorated and extremely clean. The master bathroom is very luxurious and the beds are comfy; hotel style.
The area (Sloane Square) is also super posh — safe, clean, and lots of restaurants and stores around. The Sunday market across the street was a real highlight. The tube station is about 6 minutes by foot which was also convenient.
Not everything worked perfectly — some appliances were being fixed up whilst we are there. Stairs also might not be convenient for everyone, and kitchen ceiling is a bit low if you’re tall. But Richard was extremely helpful and proactive. We had a lovely stay.
