My 4 friends and I stayed at this apartment mid November.
To start with the negatives - one of the beds may have had bed bugs. My friend and I sleeping in this bed woke up with 20-30 bites, following the exact pattern and look of a bed bug bite, however I didn’t check the mattress thoroughly so the air bnb owners claim there was none (we had photographic evidence of the bites, but not of the bed bugs).
In the double bedroom with the en-suite, the door of the en-suite had been slid so far into the wall that we simply couldn’t roll it out, meaning the en-suite had no functional door.
Other than these two negatives, my friends and I did have a good stay here. The location is brilliant for all things to do in Barcelona with a metro station right on the corner and walking distance (20-30mins) from both the sagrada Família and the beach. The cleanliness of the property was good (minus the bed bugs in one bed) and was a great space for 5 girls to hang out in to get ready to go out. Check-in and out were very easy and although the two issues that would have (probably) been unfixable during our 3 night stay, the hosts were very responsive at least.
All in all, if the beds are checked thoroughly upon entry, I would stay here again as overall we had a lovely time in Barcelona.
