I stayed at Flor and Fausto's house for a month. They were very friendly and helpful. On the next day of the arrival I had to take trains to get to my work place, and they searched best way for me. Fausto kindly walked with me to show how to get to the station, which was very helpful. The room was spacious with 2 single beds, a closet and a space for your luggage (2 big luggage can fit easily). It is ensuite room, so very comfortable to stay. The whole house was super clean and kitchen and bathroom were beautifully renovated. I enjoyed cooking as well.
The place was convenient to go to Heathrow. You can either walk (15 minutes) or take a bus (5 minutes by E3 bus) to Hanwell station, then take Heathrow Connect. The train takes 20 minutes to the airport's central station. If you want to go to central London, take the Heathrow Connect to the other direction to Paddington. I also learned some other ways to get to London by buses and tubes, which was perfect way to explore London.
There are shops and a supermarket (co-op) nearby. If you want to go to bigger supermarkets, just take E1 bus to Ealing Broadway. There are a big shopping centre and also TESCO, MORRISONS, M&S and Saimsbury's.
Overall, I highly recommend to stay at this beautiful house. I'll definitely come back!!
