Location is perfect. Close to Waterloo and Lower Marsh, which is a nice and trendy street with great takeaways, restaurants and small shops.
The apartment was clean and spacious. Be aware that there is no living room, and it was ok for us as we were outside most of the time. The kitchen was spacious though, so it can also be used to chill. The building is calm, but not very well isolated so you can hear the neighbours.
Communication with Marko was easy and fast.
A very good place to stay if you are in London a couple of days.
