The flat was accurately described in the post, and the pictures do a good job of reflecting the interior decor and space. Having the 4th floor balcony was great! I would definitely recommend staying at this excellent apartment.
Access to the Underground was easy (the flat is within a 10 minute walk to Earl's Court and West Brompton stations, and about 12 minutes to Fulham Broadway). The flat is also 10 minutes (or less) away from Stamford Bridge.
The check-in process was very straightforward (our flight was a bit late and then we got stuck with a long line-up at the UK Border at Heathrow, but Veronica's team was very patient with us - thank you!), as was the checkout. We felt very safe the entire time we were staying in this flat.
There are groceries available at a Tesco Express about 5 minutes away, and many coffee shops and restaurants also about 5-7 minutes away.
Noise was generally not an issue (though once in a while - thankfully not too often at night - ambulances will go by with sirens on).
