We loved the stay at Fabio's! Communication was so easy with him, always nice, always thoughtful. Make sure you don't miss out on the local tips he has for you! As to the apartment, the place is perfectly fine for 5 people as well (it was a short stay in our case), the heating worked really well (I always tend to get a bit cold), the apartment was clean, had everything we needed and made us feel like home. We'll surely think of Fabio's place when going to London again!
