Staying at Rajna & Zika's place was great! Very clean, perfect location: 10 minutes walk to Hammersmith station and 15 minutes to Olympia center where we attended a conference. The area is very nice, lots of shops, cafes and couple of great pubs nearby (highly recommend Draft House on Shepherds Bush Road!).
Rajna was very welcoming and helpful, she even picked up a package that arrived for me 2 days earlier at the post office. :)
