The boyfriend and I chose to stay at Fabio's in August 2017, and we both highly recommend it, there's just so many good points about it!
First of all, Fabio is a excellent host - Fabio messaged us frequently to ask when we'll be checking in and how we were doing, he was at home waiting to welcome us on the day we arrived, and he even recommended us places to go and how to get discounted tickets to musicals!
The apartment itself is incredibly centralised, we walked everywhere and regretted getting the visitor's pass because there is no need to take the tube at all. There were good eateries all around (King of Falafel has excellent wraps and Sainbury's is just a 3-min walk away).
We were having such a good time that we forgot the check-out time on the last day, but even then, Fabio was very patient and understanding. He deserves that super host medal.
