Quite disappointed with this experience, I must say it wasn’t a pleasant stay. Although the ad indicated that there could be noise in the street, it didn’t specify that there are bars and nightclubs all along the street open every day from 8pm to 3am, along with excessive noise from drunk people and loud music - which, on the contrary to what some comments may say, you can hear even with the windows closed.
We rented this place for a week and I recommend not staying there for more than a night or two. If you are looking for a nice relaxing stay, I don't recommend this place nor the Atalaia street at all.
Happy hour! Free shots! That's what you'll hear every night from your room, without exception and even on Sundays. Having worked in the entertainment industry, the sound levels easily exceed 100 dB in the middle of the night but this doesn't concern the local authorities.
Honestly, our vacation was wrecked because of this experience. Although we enjoy partying, having to walk through crowds of drunken people every day, drug dealers and pushy guy was not nice. Don't think about relaxing at the end of the day or in the morning, it's impossible. The noise also comes from the apartment above with little isolation and people stomping everywhere.

With no window in the bedroom, it is damp and the closets smell musty. The air from the street never really goes to the bedroom to air it out. The room is connected to the bathroom and the kitchen, which increases the humidity problem. The stairs are very steep and narrow, I don't recommend for people who have trouble getting around.
People don’t just pass by, they stop, drunkenly shout songs and other. Aggressive drug dealers try to sell you drugs on every corner as soon as it gets dark. Various shows to entertain you: fights, robberies, drug dealing and intergalactic conversations to witness at night from the balcony.
This is the worst street to sleep in Lisbon. You can hear the noise through the walls and the pipes in the bathroom. Alcohol fumes and strong garbage smells will keep you company when the windows are open. You'll need earplugs or a speaker with white noise all night to sleep. In summer, impossible to sleep with the windows open.
A fire extinguisher is available in the living room if needed. In terms of fire safety, it's great, but it still means that the risk is real. A person who stayed in July 2022 had his laptop stolen in this apartment and he never got it back. This gives some idea that the street isn't super safe, despite the police station one street away.
On the positive side, the apartment was clean. The location is perfect for getting around the city, everything is nearby. The weather was perfect, which is a nice if you want to escape your apartment at sunset.
