Vincent and Rachel are great hosts, the communication is crystal clear and superfast, and they are very happy to provide you with all information you want about the city. The apartment is clean and fully functional and the bed provides you all the rest you need for the next day.
Location wise, it's great too: easy access to tram, metro and bus stops, especially if you use the passages of the block. There is no need to walk to the historical part of the town because you are right into it, you can just enjoy. However, of course, like any other capital, be vigilant with your belongings.
Please mind that the apartment has a collective hallway and the toilet is separate from the apartment (but private).
I'd definitely recommend Vincent's place to any group of friends or family, specially if you are spending all your time in the historical city center.
