Overall stay was ok, location is super, close to city center and from tram stations. Studio is good comfort, with large bed and sofas.
On the negative side, heating system did not work during day, and barely heating at night in my room (16), despite being on full mode.
Also, a fire alarm was running out of battery on the 3rd floor, so bipping every minute. I told the clerk on my first day, being answered that this would be taken care of. Nothing happened, I sent a message via the application to ask for battery change to stop the bipping. Still no answer to this day, so it bipped for minimum 4 days, from Saturday to Tuesday
