Nicolas's apartment is beautiful and very well-equipped. The apartment feels very spacious and peaceful, and the location is absolutely excellent - you are very close to shops and the tube station and you can feel the buzz of the area, however it still feels very tranquil! Nicholas is a wonderful host and the communication with him was very easy from start to finish. He offered lots of excellent recommendations for restaurants/bars etc. and was generally very helpful and welcoming. He even offered to book restaurants etc. for us during the stay if we needed him to.
I would absolutely recommend Nicolas as a host, and his beautiful Montmartrois appartment if you're looking to book somewhere in Paris - it really made our stay so special and fuss-free.
