Great place to stay! The room was clean and inviting, and Marta's roommates were friendly and helpful. It's very conveniently located a five minute walk from the nearest bus stop and fifteen minute walk from the train station. It's easy to get to central London from there, and there are lots of nice shops around within easy walking distance.
The front door lock is a little tricky, so I would ask someone to show you how to open it.
I didn't get to meet Marta in person, but she was very kind and helpful via messages. Overall enjoyed my stay very much and would recommend it!
