Natalia and Lydia's apartment is really nice, modern, clean and well equipped and it is located in the perfect central and safe area of Barcelona. The bus and metro station are both less than 5min walking distance.
Natalia was always available to answer quickly to my inquiries and Lydia, who welcomed me at my check-in, was very kind, and took the time to explain to me everything.
I definitely recommend staying at this Airbnb and will definitely book it again when I come back.
