Let's start with the good points: spacious room, comfortable and well soundproofed outwards.
There was a promotional offer that I took advantage of, of course. But the problem with that was that there was a whole fauna of young people, resulting in a noise in the hallway until 11pm, as well as in the reception and cafeteria (you had to hang on to find a place). On the noise side, there is also a problem with the pipes: it is very unpleasant when the neighbor upstairs takes his shower at 11 p.m. or 5 a.m.
I did not find parking in the street and so I took the garage of the hotel at 10€ a night.
Another point I would like to draw Sercotel's attention to is their communication: I must have received almost 10 messages by email or SMS inviting me to register online. And, arriving at the reception to check in, I was again asked to enter my email address; likewise to have access to Wifi. Sercotel will understand that I was particularly upset and that they can certainly do this smarter!
One more point. You can feel like you're close to the city center, but in fact, it's practically a 30-minute walk. And the center has no architectural or other interest. The only nice thing is that it's very much alive.
