This is quite a good listing. It's spacious, with ample room for 3 couples, or a family with several children; it also has two terraces, one of which is nice to eat on (the other is dark most of the day). And it's clean and in a quiet neighborhood. There are some drawbacks, though:
1) The downstairs is very dark. Even with all the lights on, I could barely read in the living room - I needed to move near a window.
2) The furniture in the living room is too low to be comfortable. What with the dark lighting as well, it's not a nice place to hang out.
3) Kitchen supplies are OK, but have significant gaps. No decent bowls, no spatula, only two pots with covers (it was challenging to make rice) and frying pans in poor shape ... It's not a place well designed for cooking.
4) The place is perfectly suited for visiting Park Güell, but Park Güell is quite isolated from the rest of Barcelona. Unless you want to walk an hour or so, you'll need public transportaton or taxis to get to the heart of the town.
5) Communication with the owner was a bit odd, shall we say. We never met Jordi - not even sure he or she exists ... - and were instead met by someone named Alamin, who was in a rush to get going again and did not tell us how to use the stove, oven, washing machine, or DVD player. He then told us that if we needed anything, we could come up to a shop where he (and Jordi?) worked, across from Park Güell, but when we did go up there, on two occasions, nobody in the shop seemed to have heard of either of them. Not sure what was going on there, but it made me uncomfortable ...
Once again, I want to make clear that it's a perfectly OK listing, and well-suited for many.
