About the property

What makes Hilton Diagonal Mar Barcelona worth the points.

The property sits in the Sant Martí district's seafront area, approximately 550 meters from Platja de Llevant beach and within a short walk of El Maresme–Forum metro station on Line 4, which reaches the city center in about 20 minutes. It offers 433 rooms across 23 floors, including standard rooms and larger suites, with options for connecting rooms, non-smoking rooms, pet-friendly accommodations, and family amenities such as cribs and a kids' menu.

Timing

When to go.

Live · you're in July
Best time
Apr–Jun, Sep–Oct

Shoulder-season months offer mild, relatively dry weather around 14–21°C, fewer crowds, manageable prices, and good conditions for festivals and sightseeing without peak-summer heat.

Avoid
Jul–Aug

Hot, humid conditions coincide with peak tourist season, larger crowds, higher accommodation prices, stronger award demand, and some August closures.

From our review

A few more timing notes.

The outdoor pool and beach club operate seasonally, making summer months suitable for pool and waterfront access.
Year-round metro connections support easy travel to central Barcelona regardless of season.
The convention-center location suits business travel throughout the year, with added leisure options when the pool is open.
Family-oriented amenities including the children's pool are available during operating seasons.
Fine print

  • · The outdoor pool and beach club are seasonal and subject to closure periods such as a brief closure noted in June.
  • · Executive lounge access is typically available to eligible Hilton Honors members subject to program rules.
