Tina's place is excellent. Located in central London everything is reachable with a 10 min walk or tube ride from the flat.
I stayed here for a two-month stay and could not be happier. As Tina was working a lot she had one of her friends Saskia take care of most at the airbnb and it worked out very well. Got quick response to every request and upon arrival she would be there to sort me out.
Also, the flat is newly renovated and very modern with a lot of charm. Whenever I needed some local tips, recommendations or just wanted to have a chat both Tina and Saskia were very available and helpful. Whatever the reason you're in London for you will not regret staying here. In total, for me it was a great experience staying here and I will definitely recommend it to anyone going to London either short or long-term.
