The location is fantastic--it's only one block away from Arc di Triomf station. The WiFi was fast and reliable. Overall, it's pretty quiet at night. You can't really hear too much noise from the neighbors at night. Cassie is really great and prompt with her communication!
The mattress was incredibly uncomfortable. I could feel every spring in the mattress. If you're staying long-term, you should get a mattress topper. I also had to go out and buy a fan for this room just so I could sleep for the first couple of weeks.
