My stay at Maria's apartment was really great.
The room was clean, super comfortable and everything you need was there, including towels, shower gel and a hairdryer which is especially great when you are travelling with hand-baggage only.
From the apartment, you can take the bus right into the London city center or walk to the closest subway station to attend events in the city.
Maria was a fantastic, super friendly and very communicative host who was always happy to help with any question or problem.
Therefore, I can only recommend staying at Maria's place when travelling to London!
