We took this apartment only because of the terrace and we were thinking that it is our privat, but it was for every person in this building. In this offer it was not written that it is for everyone (yes, it was not written that it is"privat" but i didnt look for other offers of Elsa &Iban to see if there are photos of the terrace, because other apartments were no available then). I recommend to put it in the decription, because in our case it was most important thing, the reason we took this offer. So we were very dissapointed...
But generally: the flat is big and spacoius, my bed was comfortable. It was clean and very nice. It is a pity that it is only one shower, because for 6 person it took a long time to all have shower, but at least it was 2 toilets.
The place was great, very near to sagrada familia. Coffee, pizza and other bistros just under your windows. It is a nice view from the room and bedrooms with street view ( it is a little noisy, but when you close the window is ok)... and great ambient for sleep in bedrooms with view for internal yard - there is complet silence and part/shadow whole the day ( i loved it).
Kitchen was good equiped, even tabs for dishwasher.
Communication with host was very good. WE have no many occasion to meet, but they were elastic about arriving time and communications via email was very satysfying. They can help you to buy tickets in internet for monuments and other actvities (then you dont have to stand in horribly long queues).
So, if you dont need to have private terrac ( it have really great view) I strongly recommend this offer.
