Great location, but otherwise very modest accommodations. This is not trying to be a negative review whatsoever- just a few things for the next traveler to be aware of.
The listing states skyline views, but the only windows to the space overlook dark alleys. Also, I was unaware of additional fees that would be requested as a tax- although no other Airbnb during our time in Spain asked for such a fee.
Otherwise it has everything you need and a few extras. The hosts were great with communication and you are in a great part of Barcelona.
