We had a very pleasant stay at Olivia's house. It is quite hard to find such a huge living space in London. The lovely rooftop terrace was such a nice place to just sit and enjoy the view of London's tall and modern buildings.
The location was also quite good as it was possible to take the bus from there to the main locations in London (Westminster, London Bridge, etc) and it took only about 15-20 minutes to get there. There was also a grocery store nearby which was nice to have.
Thank you, Olivia and it was also great that we managed to meet before you went away. We got some useful tips for things to do in London, which is a huge city. Every time I come there, I always experience and see something new.
