I had a really nice stay at the apartment - especially the terrace and the location in Poble-Sec are great! The keys need to be picked up in a different location, which is good to know when booking. Unfortunately, I seems like the washing machine doesn’t work but I also didn’t contact the hosts about this so they might have fixed it. If you want to cook most of the essentials are there so this is definitely possible - just no salt, pepper etc. so you’d need to buy these essentials.
I can definitely recommend the apartment.
