I saw some of the reviews but thought I've lived in a few of the biggest cities in the world, and have stayed in some dodgy areas, I know noise, it can't be that bad. No, actually it can. It was far worse than I could have ever imagined. I can also see why one of the other reviewers mentioned he felt unsafe as I ended up feeling the exact same way -including having someone repeatedly pulling at the doorhandle like they were trying to enter and hitting the door, fortunately I always kept it locked but that was the last straw. I don't know if the neighbors just hate tourists or if this is their usual M.O. but I have never stayed adjacent to a louder, more reprehensible grouping of people. I can't imagine how anyone would want to stay here. It's way too noisy to work from home, study, or sleep even with earplugs. God forbid you have a professional call to make. All of the outside noise is fully audible and doesn't die down until 3 am or sometimes later. Some lovely individual decided to yell "shut the f*ck up!" at full volume so it sounded like they were in the room with me during my international call. That was oh so much fun to explain to person on the other line! In addition, they can hear you outside as well as you can hear them so if you have to impart any sensitive information or just simply want reasonable privacy it's not going to happen. There are gaps all along the door. I believe that's how bugs were getting in as well as impairing noise dampening from the outside. I was trying to put groceries in the cabinet and ran into Texas sized cockroach forcing me to throw away anything that was not fully sealed in plastic and repack all of my stuff for fear of infestation. In the end, I had to bear the expense and aggravation of shortening my stay in Lisbon because I was just too miserable at this accommodation and truly did not feel safe. I have traveled a lot internationally and NEVER had to literally FLEE from a place before. Staying here ruined my trip. I can't stress enough that if you're traveling alone, especially as woman, to rethink staying in this apartment. I would hate to have anyone experience the nightmare I went through. If you do decide to risk staying here take timestamped pictures, and ideally have a witness like I luckily did before you leave, as the host might try to shake you down for more money after checking out. Worst travel experience of my life! The only positive was Airbnb was very helpful.
