Mathieu's flat is amazing! It is exactly as pictured. Compared to average accommodations in Paris, his apartment exceeds expectations. It is roomy, there are two showers and a tub. Only one toilet, which for us was not an issue. I will say if you are a much bigger person, the toilet (which is in it's own room) may be a bit small. The beds were comfortable. My husband and I stayed in the main bedroom, our son in the loft and our daughter on the futon-like sofa in the main room. The kitchen is fully equipped PLUS a washer/dryer unit. We never cooked, but there is a stove too. The windows(3 of them) are quintessential Paris, so idyllic and beautiful. There are 4 huge skylight windows with remote to open/close the windows and blinds. They all let in a nice breeze after a day of sightseeing. The rooftop is AMAZING. It is bigger than expected and the Eiffel Tower looks much closer in person than in the photos. We were there for Bastille day and the fireworks view was a once in a lifetime experience. Also having the elevator obviously is amazing, especially when staying on the 6th floor! (and the fact that I got plantar fasciitis on the first full day there)
The only downside we had was that we went during the heatwave and there is no air conditioning(which is not unusual in Paris), but Mathieu did bring us 2 extra fans (there were 2 there already) to help make us more comfortable. Also, the wifi wasn't working when we arrived and with it being a holiday it took a day to get it fixed. Even after the fix it was spotty, but honestly, it wasn't a huge deal because we were only there essentially at night.
Like I said, we visited during the heatwave so we ended up on Monday getting a hotel for one night so we could sleep comfortably (all other nights were just fine, actually very comfortable, with the windows open and the breeze coming in) this was an isolated type of issue and we made the choice to do it because we had an early morning the next day and my son wasn't feeling well and of course my foot pain, we just needed to be refreshed to make our last full day a great one!
I would stay here again in a heartbeat! It is very close to the Metro, there are good restaurants nearby, the street is quiet and felt safe. Mathieu was great at communicating and always answered questions in a timely manner. Thank you for sharing your lovely home!
