We enjoyed our stay in the apartment.
Its best feature is definitely its location. The place was also clean inside and had all the utilities we needed.
The host was very responsive, genuinely nice, and accommodating.
Our only issue was that the street outside would get quite loud at night. If you have balcony doors/windows open for fresh air or to stay cool, you'll have to deal with rowdy people up until about 12:45am when the police kicks them out. But that's what you get from staying in El Born where all the best spots are at your fingertips.
Would gladly come back again to this apartment.
