I would highly recommend Elisa's Apartment for anyone travelling to London alone or as a couple. The Apartment is spotless, fully equipped with everything you could need, has fast WiFi and the room has more than enough space for two people (big bed, closet, cabinett, desk with office chair).
The Garden is also a nice option to have available for morning coffee.
Elisa made my stay very comfortable, she is a perfect host. She is a lovely person, responds very quickly and any information you could need (WiFi, check in, location etc.) is also readily available on airbnb after booking.
The location of the apartment ist perfect if you like to be active and get around when travelling. There are 3 central underground lines, 2 overground lines and multiple buses ocated within a 10 minute walk.
10/10 experience, highly recommend it!
