Oh well! Everything was pretty much as we excpected. Host was super friendly and communication was seamless from the beginning till the end of trip – and also even afterward.
Apartment was super clean and it felt great to step in clean rooms after long travelling! We were asking early check-in and late check out because our flying schedules and nothing was a problem. Just be sure to make advance what is the final cost.
Target has a great location. It's just a few minute walking to Sant's Station where you will get a ride almost everywhere in Barcelona. There was an idyllic home street and it was very nice to stay along locals.. There wasn't too much tourists around the corners. I really doesn't want to meet Finnish people everywhere :D
There's also good reason why apartment is not allowed for party groups because sound absorption is quite mild.
Overall we had very good experience to stay here. :)
