My girlfriend and I stayed for 2 nights at Eamonn's flat. The room was lovely, we had our own bathroom. He also provided bath towels and we could use kitchen to cook meals and have a cup of tea :) His cat is really nice and friendly too.
There is a Tesco Express shop at the corner. This flat is 40 minutes away from the centre and it is situated near Sudbury Town station on Piccadilly line (the best line if you want to get to the centre).
P.S. Eamonn thank you so much! We had a lovely weekend! We will definitely choose your room if we go to London again.
