I had a lovely 4-days stay with my mom in Alex's apartment. The room looks exactly like the picture. I haven't had the chance to meet him in person but he gave me a lot of advice before our arrival and was very helpful and accommodating.
However his roommates were there to greet us. They were extremely nice and welcoming, and fun to chat with.
Also if you are french: every one in Alex's apartment (including himself) speaks french on some level which can be really helpful.
10/10 would recommend
