We loved our stay at Mathieu's apartment! It was perfect for 3 nights, lots of space for 2 people. It was in such a great location for exploring Batignolles and Montmatre, and only about 30 mins walk from more central touristy places- course nearby transport links get your there too (bus to the Gare du Nord is minutes away - ideal for Eurostar) We were met by Mathieu's housekeeper Saida who was lovely and helpful, and Mathieu was very keen to accommodate and quick to answer emails. Even for 2 mid-twenty-somethings the 5 flights of stairs you have to climb are abit of a killer but welcomed after consuming copious amount of cheese and bread! Also definitely worth it for the views of Parisian rooftops and the Eiffel tower! We would definitely stay here again!
