Bella's apartment is located on the second floor, without an elevator. The flat is very cosy, clean and has everything you need for a great stay at London.
The tube is nearby (District Line) and from the bedroom you can look onto the railway plattform (South Western Railway). Although the windows are closed you can hear the sound of the trains. I didn't mind, but if you are sensitive to noise maybe you should use earplugs during sleeping.
There are many shops, restaurants, supermarkets and an ATM on foot the apartment.
I really enjoyed my stay and could definitely recommend Bella's apartment for having a good time.
