Overall, we had a positive experience at Natacha's flat. The check-in instructions were extremely detailed and helpful, the flat was clean and well equipped and it was exceedingly spacious. The location was also excellent - very close to two tube stops and surrounded by an abundance of restaurants and coffee shops.
We did have a few issues during our stay. When we checked in, half of the lights were not working. Andrew, Natacha's lovely upstairs neighbour, came to the rescue, but we still didn't have lights in one of the bathrooms for several days. We were also unaware that this flat was located in the basement. Just a heads up if that might be important to you.
Overall we thoroughly enjoyed our time in London and our stay at Natacha's.
