awful . very dirty, not the same as it is describe both in pictures and text descriptions.
first of all, the shelf was full of dirty pillows and towels, and one part of it was locked!. so you literality have no space for you bag or cloth( even no hanger), and you should leave your stuff and cloth on the ground!
second the left bed was just a mattress, nothing else and different from the picture. and it is so soft that you can't sleep on it. literality it became one inch if you push it or lie on the it.
third, the place was so untidy and dirty. my pillow was dirty and there were lots of dirty pillows and towels. some towels were on the ground both in room and bathroom.
fourth, in check in, the owner asked us to wash our dishes as soon as we used anything, which is right. but the kitchen sink was full of dirty dishes when we arrived and when came back at night. so also dirty and untidy kitchen. we didn't use the kitchen at all because of this.
finally, about the communication, the guys doesn't seem nice, and a bit grumpy. I don't know if it was because his English wasn't good or he is just like that. Also, why someone should be unwilling to give WIFI password, when it is supposed to be provided! why are you asking if we need internet! just print the password and put it in the room. Anyway, I didn't use his internet, my friend did; so I don't know about the its speed.
about the location, I it's far from all the attractions.
one good point was that since nobody booked the place after us, he let my friend keep his bag at the place and take it later "at night". but at night he aggressively texted me where is my key and where are you! I really don't know if he forgot what he said, or again it was a communication problem. nice gesture, but at the end weird!
overall, my experience suggest even a hostel!, even not a good one, some where within beach line, magic fountain, and cathedrals is much better than this to enjoy Barcelona.
