We had the most lovely stay at Royal Lancaster. A family of three, we had a great corner room that was very comfortable, both the main bed (especially) and even the twin- which usually these are not so comfortable. Everything was immaculate and the rooms were very convenient in closet and drawer/wardrobe space. Residential area which is nice and quiet , right across from Hyde Park. The breakfast buffet was wonderful, recommend to try it. It has many nice options, both healthy and indulgent. Doreen, the manager, is absolutely amazing. She is so warm and pleasant, and made our stay absolutely perfect. They gave us a nice welcome birthday amenity (mini cake) and fruit and had our room ready as quickly as possible. Everyone is lovely and the property is modern (bathroom is a bit smaller but nice) and clean, and overall just wonderful. The automatic day and night shades also helped for these long summer days. I would highly recommend it for all ages. It is not in the middle of the bustling areas which we liked. But, you can still walk to things (probably about 20-25 min to Marble Arch etc) and take a taxi. 5 stars!
