The host was very accommodating, she even sent us to the airport at 4am in the morning right after picking up another tenant at 12am that day.
Now about the apartment -
It's a clean apartment with clean towels and everything you need, but it does have some inconveniences. The lift is not completed yet, so my wife and i always have to carry my child and things we buy up the stairs to the third floor.
And the washer is on the terrace one floor above you, so you have to plan really well before you go do your laundry, but it does beat drying your clothes with the time you probably have while on vacation.
The room is a little small with no door separating you and the living room where my sister is sleeping, just separated by the wall cabinet so she probably complained about my snoring after the 14 hours flight. LOL
Overall it was a great experience and i would definitely come and rent this apartment again if i were to come to Barcelona. Alba is always near to help as she and her bf lived right next door to us and using an Iphone so i would sometimes send her an imessage requesting some help.
