The flat is wonderful place to stay. Much better than we've expected.
Near the house there are several transport stops that you can choose to get to the center. Different bus paths and the tube.
There is also quite big Sainsbury's store to buy some food, skin care products.
There are all kind of home appliances inside the flat that necessary. Nice heater inside the flat can be used if you like temperature a bit warmer or colder.
Jolly is a nice host and answers quite fast so staying will be comfortable.
