Not great.
Check-in was more than 1h40 later than the announced time. I understand this was due to the ongoing renovations, but it was still a long wait, especially as I had work to do.
What I found disappointing was the lack of flexibility at check-out. I waited 1h40 for my room to check-in, but reception couldn't show the same patience and give me even 5 minutes. At 11:04, just four minutes after check-out time, I was called and told to leave immediately. Given how patiently I accepted the delay at check-in, I found this unnecessarily rude and impatient. I wasn't asking for an extra hour, just a few minutes of basic courtesy.
During my stay, painting and renovation works were taking place. There was a constant smell of paint, some noise, and getting to my room was more difficult, with plastic on the floor and the trying to be careful not to get clothes dirty with fresh paint everywhere. I understand renovations are sometimes necessary, but guests should ideally be informed beforehand and, preferably assign rooms away from the works.
The staff kindly left macarons and an apology letter in my colleagues' rooms. I didn't receive anything in mine.. which I assume was simply an oversight.
The elevator was also inconvenient: it could only fit one person with one suitcase, and it didn't stop directly on every floor, meaning luggage had to be carried up or down several steps. Baptiste from reception kindly helped me with my luggage to get to the first floor, which I appreciated.
