Katie was a wonderful host, after a warm welcome she gave me information on the surrondings - communication in writing was also fast and reliable.
The flat is really big - there is large sunny terrace and nice furniture. The bedroom and the bathroom as well as a balcony in addition to the terrace are on the second floor. The bed was very comfortable, I always woke up well rested. It is true that there is some airplane noise, which didn't bother me - during the night it was silent. The height of the bathroom was no problem for me (1,70m). It takes about 10-15 min on foot to the underground station Parsons Green, from which you have direct connections e.g. to South Kensigton (Victoria/Albert and other museums), Victoria (Buckingham Palace, buses e.g. to Oxford, airports), Westminster, Embankment and Notting Hill with the District line. With the Piccadilly line from Earls Court e.g. Hyde Park, Leicester Square (Westend performances, Soho, close to Travalgar square and National Gallery) and King's Cross are easy to reach. There are two supermarkets very close to the appartment and some cafés. The neighbourhood is very pretty with traditional small Victorian houses.
I recommend staying in this flat!
