Gil was a great host, even way before the trip. He took effort to provide details about his place and other information two week prior to my stay at his place.
Gil was there to welcome me and explained all the amenities available at his place and how to use them (e.g. washing machine, dryer, microwave, shower, etc.). Throughout the stay, Gil provided some updates along the way and checks in to see if I'm alright. One of the lifts was down and there was water servicing during one of the days and Gil was able to inform me about the status and ensured that we have water to use during the water service period.
Location wise, it is very convenient to get to Bermondsey station from Heathrow. If you worry about carrying luggages, the changing and destination stations have direct lift links (Bermondsey station has direct lift to ground level). Within few minutes of walking distance, there's Tesco Metro, providing all your necessary food or daily use items, and they open till 11 pm daily (closed on Sundays). From the room, I could enjoy London's view of Tower Bridge, The Shard, London Eye, to even the tower of House of Lords.
Overall, I felt very comfortable staying at Gil's place and will definitely return again on my next trip to London.
