Make sure to contact the host directly and they know exactly what time you arrive. We told Peter that we will arrive at noon and when we got there he was not. There was a lot of miscommunication and ended up that we tried ringing different doorbells which eventually Peters dad opened the door for us.
Be mindful of steep stairs going up and down the building. It felt like more of a hike. For older folks, I don’t recommend.
Bring earplugs if you cannot sleep with noise because the tower clock rings every 30mins and you can hear everything happening out the street.
Overall the place was clean and location is superb for visitors.
