The flat was very clean and spacious. The bed linens and towels were super clean too. I was very comfortable staying for 5 nights. There are several places to eat close by. The nearest Underground station is about a 10 minute walk but I didn't mind walking at all. There are also bus stops right around the corner depending where you want to go.
I walked to several different areas including Notting Hill/Portobello Market. Communication and self check-in and check-out was smooth.
