This apartment had a few pros and cons:
The pros - the location and the space!!! GREAT location - easy walking to the historical center of town and the metro. It was awesome. And the space . . . it was huge.
The cons - there is one wall a/c unit in each side of the apartment. One does not work at all and the owners have known about it since July (see previous AirBnb review). They did not tell us about it before checking in even though Barcelona has been very hot and they knew we had small children. We absolutely would have looked for another accommodation. Further, they told us at check-in that even though the air conditioner in one living room was working, the ones in the bedrooms were working and there were extra fans. Both of those statements were not true. They were very nice as we went back and forth during our stay about the air conditioning and offered us 10% off of the price, but that does not make up for the fact that half of us slept on a tile floor near the working a/c unit with couch cushions for 4 nights . . .
In addition, the main bathroom stinks badly and looks to have mold around the edges of the shower, the large coffee appliance has rust in the water basin, which made it unusable, and the apartment furnishings were very run-down. In general, the apartment has potential and you can tell that it was cute at one point, but it is not in good condition.
We were very disappointed with this apartment.
