Felix is a very nice guy. We texted a lot in advance, because I had a million questions, but he never got annoyed.
Checking in was easy since he was at home and awake, although it was pretty late in the evening. We enjoyed the large bed and our quiet room. After an exhausting day in London there's no better place to be than your "own" room. Also being allowed to use his kitchen was great.
I can highly recommend his place for everyone who doesn't care to travel a bit by train to central London!
