This apartment (with a balcony!) is a gem in the middle of the Gracia district -- close to public transport, grocery stores, restaurants, and also interesting local shops. We also found it easy to hail a cab from its surrounding roads, which is definitely helpful during these post-COVID times!
The place was clean and has all the necessities; the bedroom also faces away from the main street so it was quiet at night. I'd definitely recommend this place if you're in Barcelona.
