Matthias is a very nice guy. Anytime we communicates, he answered quickly and assisted in a pleasent way.
He also gave me a detailed information how to get to him. Furthermore, it was possible to change the arrivaltime, that was really good for me, because I arrived in the evening.
Regarding the flat a can say, that he has a realy warm and nicely arranged apartment. I felt like at home.
The area around is alive and multiculturel. You are directly (300-400 m) behind Sacre Coeur and also in the heart of parisien life. You have a lot of bakeries and restaurants around, so it won´t get be boring.
For me I can say: I really enjoyed my stay at Matthias and I can really recommend you Matthias. If you take it, you won´t be disappointed, for sure.
