Sorry, that is not the heart of Chelsea, it’s definitely the cheap end! It’s definitely not prime central London, not by a country mile. Have you actually been down there? It’s by the Worlds End estate, not the nicest place. There are of course some nice streets in SW10. That isn’t one of them.
£1,100 will NOT get you a lot in the heart of Chelsea, as I previously said, it’s a basement or a short lease.
Prime Chelsea, SW3, Sloane Court West and East. Smith Street, Dovehouse Street, area around Chelsea Green (NOT Sloane Avenue). That list is not definitive, it’s just what popped into my head.
I have lived in the area for years and years, and know what I am talking about. I am pretty sure though that you won’t accept that someone that actually lives in the location, has done for years and has had a number of flats in the SW3 postcode doesn’t know what they are talking about.
