Gloria's house is very big and comfortable. Well communicated with public transportation and in a very good neighborhood. It was better than you can see in pictures and even you are surrounded by nature (we saw a fox in the backyard).
Gloria is a very nice and warm host and she gave us information to get our electric plug adapter for a very good price.
The place is located 30 min by train to the city center of London (London Bridge station) and is very easy to get from there to all tourist attractions.
If you want to get to a quiet place near to the city center I will recommend this place.
