Sunny and Gabriel are wonderful hosts! The place is airy, well-lit, and in a lovely bustling neighborhood where you see locals get dinner in outdoor-patio restaurants every night. The apartment is a mix of modern and historical – there are lovely wooden ceiling rafters, but then a modern renovated gray-marble-tile-style shared restroom.
Temperature: We were in town during the biggest summer heatwave to hit France in centuries, but remarkably, the room was cool enough! (There was no AC but the shades helped)
Getting around: The subway (after you enter the subway) was at first a little confusing to navigate because we are from a different country (language barrier) but once you get the hang of it, it's super convenient to get around quickly. The Louvre and museums are also just a 20-25 minute walk away.
Perks: They have the sweetest, friendly little dogs, and I was IN LOVE with them during our stay. They don't get in the way, you can easily shut the door, but if you love dogs like us, you'll be in heaven!
The only thing I would note is that because it's a historical/older building, there are some things you might not anticipate: the elevator is only large enough for 2 large suitcases and a carry-on. Wasn't a problem for us (we travel more light) but just good to know. Also, the floors will creak when you walk, which is natural for an older building. But if you're super sensitive to that, might also need to take it into account.
