The apartment is really nice, comfortable and well equipped - everything what you need for few days stay in London. There are 2 underground stations about 15-20 minutes walk - elephant&castle or kennington. You can also take a bus which is closer or even walk to tower bridge. There is also street market open everyday - you can buy there fruits, vegetables, meat or fish. Big supermarket is also not too far away.
Kyle is a lovely host, always responding quickly and very polite.
My stay in London was just perfect, thank you Kyle :)
