Me and my friend had a beautiful trip there. Mari is very hopefull (we came late at 1am past and she has waiting, to welcome us).
The flat is very near from the center 20-25 at walk from London bridge.
Near the flat you have many restaurants to eat and the bus station too.
If you have any questions or any problems Mari is here to help you.
Thank you for everything it was a beautiful experience for us !
Hope too see you maybe :)
