I enjoyed my stay at Marie's a lot. It's very conveniently located - you can easily walk to the Big Ben & Borough from there, while being in a quiet and peaceful area.
Marie was very accommodating in that she allowed me to drop my bag at the place in advance and let me check out a little later. There was also a problem with the internet that she was very quick to address. The communication with her was also super prompt.
One thing to note is that there are quite a few rules in the house and there's two surveillance cameras at the property. This is clearly indicated in the description of the listing though, so as long as you're aware and ok with it, you'll be fine.
The other 2 flatmates staying at the property were wonderful people.
Thanks Marie & Val!
