Pepo was the great host. He met us exactly at the time we agreed on even if he was on another meeting just before. He was very friendly, and showed and explain about near all facilities in the appartments.
The apartments were really nice: clean, fully equipped with furniture, and even some oil, salt, etc - if you'd like to cook in Barcelona of course :)
I should it was quiet place, no noise around, etc
Balcony is OK for 2 person to spend a night talking with a glass of wine
2 major things you need to be aware:
- there is no elevator in the building (but Pepo helped us with our luggage when we arrived)
- hot water comes from the boiler (75l) so if you're a couple or family of few persons - keep this in mind when planning 'shower-time'

and of course - location is amazing, few hundred meters from Sagrada Familia (and subway nearby)
2 grocery stores are in the neighbor buildings, farmacy, flower shop, ...

We enjoyed staying there!
