The appartment was very nice! Sure, it losts a bit of it's glamour in the time between the pictures and now but which hoteltoom doesn't. It's very central you can get to pretty much anything by foot. Also the bar underneath wasn't bothering us too much. I just slept with earplugs and was fine. My mother and boyfriend weren't bothered sleeping at all. Thete is a huge balcony where you can keep an track on the line of people waiting in front of the Livraria Lello and also just overlooking the area.
Our check-in was reschedueled earlier than first planned and we where very thankfull for that. They replied very fast to every message per whatsapp or airbnb.
Keep in mind that there is a ''secret'' door between the two bedrooms in the cabinets connecting them, the door is not very isolated. So it's not as private as you might wish.
I would definitely recommend the appartment!
