Believe everything you read in the description. You will climb stairs to get to the flat and then you’ll climb more once inside. We are both in are early 60’s and averaged walking over 6 miles a day for our entire trip of 4 weeks and we did fine. The kitchen is functional, but don’t walk in expecting a place where you can cook like you do at home. The bath had a nice sower and plenty of cabinet storage. The dining table is pretty small, but quite functional for two people. The living room has a nice size tv and two comfortable couches and the bed was wonderfully comfortable though quite low. The washer/dryer is a one machine combo, so if you’re unfamiliar with such machines, be sure to read the instructions provided.
As for the neighborhood, Earl’s Court was great. The subway station was an easy walk in under 10 minutes. A major supermarket, pubs, ethnic restaurants, and cash machines are all on the walk from the station. It was quiet in the building and on the street at night, so we slept well.
One last note: don’t be put off by the many rules put forth by the owner. None were difficult to follow and he was always quick to respond to questions. And best of all, his place is ACCURATELY described on the site.
