This was a really cute apartment! I would totally stay here again! The ceilings are a little low, so maybe not the best choice if you're a taller person, and the stairs up from the entrance are pretty steep, so maybe not the best choice if you have mobility issues. We were totally fine though!
It was exactly as it was pictured, and was nice and clean when we got there.
The tube ride seemed a bit lengthy, but it was really easy to navigate, so that was good.
All in all, Carl's place is a great home base to explore London from!
