Val is very friendly and helpful, I think a further story speaks for itself better. Our connecting flight had been delayed due to an electromagnetic storm, Val waited for us in the apartment despite the fact that we were late for 4 hours. She was always happy to help in the mornings and give us some tips if we had any questions or concerns.
The apartment's location is perfect, it is located in 2 minutes by foot from one tube station and from there you can get to every place you need. If you like walking like we, in 10 minutes you can get to the Tower and Tower Bridge.
Finally, what a beautiful view you will have from the balcony, I couldn't believe my own eyes when I saw it for the first time :)
Long story short, highly recommended!
