I don't know from where to start,
first, Gianna is the guy who welcomed us, our checkin was very smooth and given very clear instructions about how to use every single thing from the entrance of the building to the apartment to the appliance to every single small thing.
we sat with Gianna and he gave many options about where to go in Barcelona (as this was our first time to Barcelona), how to use the metro, buses, taxi, and many other activities.
it is the most beautiful apartment i have ever seen (my family in the first day they don't want to go and roam barcelona, they wanted just to sit in the apartment to chill).
everything was more than perfect
i would recommend anyone visiting Barcelona to always book this apartment with those beatufil hosts which they will make your life easy and your trip very smooth.
Thanks alot Gianna and Frederic, you made my trip more than perfect !
