Pros:
I only talked to Pierre over the phone and he sounded very nice and reasonable.
He organised a company to handle the check-in/out process. They were reliable and responded very fast even at weekend or after hours.
The Apt. is very modern and clean just like the picture.(The picture look a bit bigger but I guess nowadays everybody uses such wide camera lenses to show the room bigger, which I myself find it a bot dishonest )
Internet is very fast and stable.
Location is very central and convenient.
Cons:
By check in the e-key didn't work which can happen, not a big deal but the person in charge didn't have an extra key. So we had to wait about 45 min until a neighbour came out and open the door for us.
By check out they were a bit inflexible, I asked them if I could check out 1 hour later, but unfortunately it wasn't possible. But to be fair they mentioned that the check out time was 11. But in my experience, hosts are usually flexible with the check out time.
Conclusion:
Altogether we had a really good time and the Apt. lived up to our expectations. That's why I gave it 5 stars. I definitely recommend this place.
