We stayed 12 days with our 4 young kids. Great location, near the hustle and bustle but a very quiet area. Watrose right around the corner, Herrods and Hyde park close by, wine shop and fancy dry cleaner next door. All made life very convenient. The 3-bedroom unit we had is bare bones. It's recently renovated and clean, but not high end. The bedrooms are very small but workable and have plenty of storage space for clothes and luggage. It's the top floor of the building so the windows are very small. The bedding was a hodgepodge--sheets were crisp but the covers seemed ratty. The kitchen is very small and the dishwasher didn't work great but the every-other-day housekeeping kept the unit clean and restocked. AC was excellent and there is a thermostat in each room. The neighborhood is very fancy, clean and quiet, but the building next door and the street adjacent to the building (which is on a corner) are dumpy, if that matters to you. There is 24 front desk staff who are helpful. Note the terrace in the unit is not suitable for children as it's on the fourth floor and the railing isn't very high. I wish there had been a note about that on the listing as I would have chosen a place with outdoor space that was safe for kids. We had a fine stay but probably wouldn't go back.
