Upon arrival, we had to wait 20 minutes at an empty reception before someone came to give us a key. By then, drugged guests had walked in and out the lobby several times. When leaving the elevator at our floor, the smell of cigarettes and weed overwhelmed us, and because of the large gaps under the doors, we had the same smell in our rooms. In the evening and until well after midnight, a group of guests on our floor that occupied several rooms was constantly switching rooms, slamming the doors and shouting, but even if they would've whispered we could've heard every word because of the poor acoustic insulation. When they finally went to bed, a loud fight in another room started... When complaining at the reception, we were promised someone would come over and check, but they never did. We basically spent the night reassuring the kids while going through the cancellation conditions and looking for an alternative hotel for the rest of the week (the decent wifi was pretty useful after all). Luckily, in the morning, someone at the reception felt bad for us just enough to not make a big fuzz about a cancellation and reimbursement. Well, other than that, the location was great, right next to the metro station, and it's too bad we didn't have the opportunity to try the swimming pool, but knowing the poor state of the rooms our hopes weren't too high anyway.
