We had 5 nights at this charming apartment. It is just as in the pictures. It's not massive but it's perfectly fine for two people and the space is used very well. We had everything we needed and it was very clean on our arrival. The fan in the bedroom was nice on hot evenings and the outside space is nice too.
As others have said it is up 3 floors so less mobile people may struggle . The location was fine , about 20 mins to Sagrada Familia ( a must ) and same to Park Guell ( another must ).
To walk into the Gothic Qtr and La Rambles was a bit further but the Metro is clean , fast and cheap and a station is just around the corner .
We liked the apartment, it's quirky and charming .
Thank you
