We’ve stayed at many Airbnb’s over the years and this was one of our least favourite. It’s fine and as described but run by a large company that operates like a hotel but without the warmth or experience of one. The flat was sterile with no personality, we had issues with a clogged shower and they only provided 1 roll of toilet paper for 4 people for 5 days. We were also expected to clean up after ourselves including taking out our own garbage. The shower was fixed quickly in their defence but the whole experience was just mediocre. Sito was great through communication, check in was easy and the place was clean hut we won’t be returning. The price difference between a hotel and this Airbnb doesn’t justify the experience.
Also note that although only 10ish minute walk from the Sagrada Família, it’s on the “wrong side” of central Barcelona and walking anywhere for food/drink took much longer than expected. It is close to the metro so if you’re ok taking the metro everywhere, it’s fine.
