Cozy, adorable apartment in a great area. Convenient to great restaurants, sights and the metro. Gracia is a great place from which to explore Barcelona.
The air conditioning worked wonderfully which was great given the heat wave in July. Also, the hosts were great at proactive communication and arranged to let me check in and grab the key early while the apartment was being cleaned so I could enjoy my first day in the city.
I'd definitely read the apartment rules ahead of booking (I didn't) as the terrace is shared with the building rather than private for the apartment and you are not supposed to use it after 9pm as the neighbors are particularly sensitive to noise. Not a huge deal but worth knowing so you can manage your own expectations.
Would definitely stay here again.
