Unfortunately the words disappointed and frustrated sum up our stay here. Although the location was good, we had issues with the 14 rubbish and recycling bins outside, which were collected every night between 1:00 - 2:00 in the morning. Not only effected my sleep, but it made a complete mockery of their "Silent Hours" policy between 21:00-09:00 and no music at all during our stay, so not to upset their neighbours. Wow enjoy your holiday!
The other issues were...
The shower was frustrating to use, trying to get the slightly mildewy shower head to function without the waterfall shower head dripping was one issue, but with the blocked drain you'd soon be wading around the shower tray as it filled up with water. The toiletries that were provided were leaking all over the shower tray and was anyones guess what they actually were, as they weren't labelled and did not preform any duty. Bring your own, as these ruined by hair. This was clearly an ongoing/previously occurring issue as the evidence of the water damage on the walls and door frame was quite unsightly.
The sofa flaked all over us and the floor, when all we did was sit in the rather uncomfortable thing. The dining chairs had already peeled. The water damage around the apartment was unsightly and in general the apartment could do with a bit of a make over. You would bang your head on the stairs every time you'd make a cup of tea, due to the design of the kitchen layout being under the stairs. And finally the bed squeaked every time you moved. Due to the mattress being a full memory foam mattress, you were fighting against the pockets you'd previously created, I even thought the bed must be broken on the first night, until I investigated the following morning. But most importantly the mattress and it's "lovely waterproof plastic cover" made you sweat! Although there was not the same level of cover on the pillows, as there were no protectors.
To sum up, sadly this was not a luxurious apartment, whether it once was I cannot say. The cheap furnishings were all well past their best and in need of replacing. This is the most expensive place we've stayed in and yet the most disappointing. Much smaller and less luxurious. I cannot be certain whether this is a reflection on the host or Barcelona itself, which may command a premium for what you get. All of my issues have been reported, so hopefully in time this place will improve.
