Najla's place overall was okay.
The pro is the location. GREAT location!! Near shopping such as Passeig de Gràcia which is a nice long street and lots of shopping, also not too far away from the Arc de Triomf, La Sagrada Familia and her place is about a block from the metro. Location is central to everything which made it awesome!!
Cons:
-Dusty and black hair everywhere (my girlfriend and I have blonde hair) We had to use the toilet tissue to clean up the dust and pick off the hair. She gave us about 2.5 toilet tissue rolls for a 10 day stay and when asked if she can have someone bring some more she stated "This is not a hotel" which is true, but if it was clean then I would not have been using all the tissue to wipe down her place.
-Dishes were a bit dirty so make sure to check them before you use them.
-Water is lukewarm even when you shower. It does not heat up as much as you'd like it to, the water heater went out but she had someone come and fix it which was good because the water was FREEZING, but honestly it doesn't warm up very much so all the showers we took were quick.
-Space heater was not working, it was cold and the space heater wasn't working so it was pretty cold during our stay.
-Mosquitoes in the house, not sure where they were coming from since we kept the windows closed and we only open the front door for couple seconds before we go out..
Also she provides you with minimum just 2 towel and blankets, no bath mat so floor can get wet and you can slip since tub is high up and no railing. We had to buy a small towel because there was nothing to wipe the floors after the shower.
Overall we were happy with the location that was the highlight of the whole place.
