I spent a whole month in Mathildes appartment and was very comfortable there. Mathilde is a very cordial and welcoming host and we got along really well with each other. In the appartment, I had a small but comfortbale room and shared bath and kitchen with Mathilde (like in a flatshare). The appartment is located on the 12th floor of a high building, offering great views. It has a good situation in Bordeaux such that Talence Univerity and the City Centre can be reached by foot in 15 / 25 minutes, but there is also a good connection to tram and bus.
All in all I really enjoyed my stay. I recommend Mathildes appartment for a weekend trips to Bordeaux as well as for long-term stay.
