I was trying to avoid company-managed apartments in my three day stay in Barcelona, but this is one of them. Although towels were provided and the apartment was very clean, there was no toilet paper provided (which when arriving at 1am truly stinks).
We were very kindly greeted by Albert, one of the apartment managers, and paid a 20€ late check-in fee (past midnight). The neighborhood and apartment are extremely pleasant, although staying in a non-AC apartment in Barcelona during the summer is fairly rough. Luckily, there were fans available to make it bearable.
The kitchen & apartment layout are great, wifi is good and there is only French TV channels. Barcelona is an expensive city but the listing should be more reasonable. Fanny, the host, is extremely responsive and tended to an extreme issue we had with the shower, which flooded the bathroom area (though now they're fixing it). She offered almost 10% back of what I paid on her own impulse, though it should have been a good deal more.
The center of Barcelona is a 10 minute metro ride away and the neighborhood has plenty of great restaurants and shops.
