This is definitely an economical, and clean, option. There were five of us (wife, husband, father-in-law, and two kids 12,10) and the bedrooms were fine but common area is tiny. Of course, you aren't going to BCN to hang out in the apartment but still - there are times when you are all in apartment and it got crowded. It's also not exactly in a neighborhood you are going to want to hang out - was perfectly safe but not much going on and a 15-20 minute walk to great food, drink, locals (as much as you can have locals in BCN).

The place had a hostile feel to it, which is great if that's your thing - there are a bunch of places, this was a 3 story walkup, and the balcony overlooked a courtyard of sorts where a lot of loud, tourists were doing I'm not sure what, other than smoking. It wasn't at night, just during the day.

The "host" was absolutely wonderful and spoke to us for 20 minutes when we arrived and wifi was stellar.

So if you are on a budget, I definitely recommend this place but if you can expand your budget, I'd look for a better location and bigger common area.
