We enjoyed our stay at the apartment, there are good transport options with the metro almost right next door and walking distance to the Latin Quarter. We did however have some problems with the shower being cold for the first two days, but the last two it worked fine. The shower was also not the same as on the pictures. Furthermore, there was an unexpected rule about not putting toilet paper in the toilet, but putting it in a tiny trash bin, otherwise the toilet would break and it costs 120 euro to fix.
Overall fine place to stay, bed could also be better, I personally felt it was very hard and woke up with back/shoulder pain all days. Also it was pretty small, I’m 1.85m and I couldn’t really stretch my legs without hitting the wall.
