Martin and Petra are a lovely couple and it was a pleasure staying with them. I only stayed one night as I needed somewhere in London close to transport to Heathrow Airport. Their flat is only a couple of minutes walk from Northfields underground station on the Piccadilly line - only about 20mins by train to Heathrow - very convenient! The bedroom and bathroom were spotless - very clean. And toiletries and tea were provided which was nice. They gave me an amazing pizza restaurant recommendation and were up for a chat. They're a really nice couple to chat with. Would definitely recommend!
