The staff is the best part, they're really helpful and lively. The beds and dormitories were good and the bathrooms clean.
The area is walkable and close to a lot of restaurants and bakeries but it's definitely not quiet. I've been there while the new metro line was being built, the construction went the whole night and during weekends the bars and restaurants attract enough people to keep some noise all night. Nothing unbearable but if you're a noise sensitive person, some earplugs will help.
