Horrible Experience!
This hotel is located right next to the metro station - it seems convenient to exit the hotel and enter the station, but believe me, we couldn't rest at all. For 24hours, you can constantly hear the metro on the tracks every 3 minutes. The cars, the honking - everything! There is no sound insulation at all. If you can believe it, they gave us 4 different rooms, even on the side further from the metro, but it made no difference.
Light comes through the blinds, so you can't rest well either. It was awful.
A bit of context:
Initially, I was shocked by how many cheap hotels there were. I didn't understand why and if they were of good quality, but later I understood how they could have such low prices. The rooms are tiny. It was one of the cheapest in the area, around 80 euros per night. Be warned - you will be shocked when you enter the room. The room is so small that you barely have enough space to open your suitcase. The bathroom is okay, but also extremely small. The cleaning staff are required by hotel policy to clean almost daily, so no one will respect your sleep hours if you want to rest later.
