The host’s office is very close to the place, they are available and super helpful 24h/day. They are very friendly helpful with everything thing you need.
Location - perfect, 7 mins walk to Placa Catalunya, about 25-30 mins to Barceloneta - very central, walking distance from most sights.
Building is in great shape, apartment is also new and clean. The 2 bedrooms have the bathroom in between them, creating separation. Beds are reasonably comfortable.
Definitely recommend Pisa Apartments as a host and this particular unit.
Extra perk - there is a great coffee shop at the bottom of the building with amazing coffee.
