178 Ifield in Earl's Court is a wonderful location and a first-rate place to stay in London. Its three bedrooms make it an ideal place for three or four people travelling together (or for a family). The "master" bedroom is spacious (double bed), and its bathroom is well done. The other two bedrooms--one with two twin beds, one with one--have good storage. The bathroom shared by them is perhaps the smallest I've ever seen--almost a pocket bathroom--but it works well for its purposes (assuming you are not a rotund person). The only drawback is the necessity of stairs--three flights. The kitchen and reception room are very well appointed; and the balcony at mid-level looks out on gardens and a cemetery--and is a good place to sit and for afternoon tea and snacks.
Sara, with whom we negotiated the rental, was wonderful. When she learned that we would arrive after the 9pm check-in time, she arranged for a cab to pick us up at Heathrow, give us the keys, and bring us to Ifield.

178 Ifield is perhaps a ten-minute walk to the Earl's Court tube, served by the Picadilly and District lines--and these make most of London readily accessible without changing tube lines.
Neighborhood places to eat: Primrose Pub is wonderful. Paul's, a French place across from the Earl's Court station (Earl's Court Road entrance), is very good indeed for sandwiches and sweets--take-out or eat there.
"When you're tired of London, you're tired of life," said Samuel Johnson. He is right--and 178 Ifield is a good retreat from the daily wonders.
Note: Don't neglect the Design Museum on Kensington High Street--and two wonderful Italian restaurants across the street and a bit farther on. Museum is new to us--and it's wonderful
