Hotel SB Diagonal Zero 4 Sup
Barcelona, Barcelona, Spain · ★ 4.1 Exceptional B.Booking.com 8.2
Warm water, jets bubbling, the bed a world away. Hotel SB Diagonal Zero 4 Sup's in-room hot tub sits steps from your pillow.
There's something quietly perfect about a hot tub that doesn't require you to leave your room. At Hotel SB Diagonal Zero 4 Sup in Barcelona, you'll find a hotel with a private in-room hot tub that sits right there on the wooden deck, jets running, steam rising while you're still in your clothes deciding whether to get in. The tub's built into the room itself, which means no robes, no corridors, no timing it right. Just you, the warmth, and the bed visible over your shoulder if you want to watch the morning light change.
Guests rate the place 8.2 out of 10, and the suites come in three flavours: the Suite with Hot Tub, the Deluxe Suite with Spa Bath, and the Suite with Spa Bath. All three give you that same private water feature in your space. It's the kind of thing that sounds small until you're actually in it at 11pm on a Tuesday, alone with the bubbles and a glass of something cold.

Questions, answered
Is the hot tub really in the room, or is it on a balcony?+
It's in the room itself, on a wooden deck. You don't have to step outside to use it.
Which suite type should I book if I want the hot tub?+
All three suite types (Suite with Hot Tub, Deluxe Suite with Spa Bath, and Suite with Spa Bath) feature the private in-room hot tub.
How do you verify the tub is in the room in Barcelona?+
We check with each property that the jacuzzi, hot tub or plunge pool sits inside that exact room or its private terrace, never a shared spa, before the suite shows up here.
Are the tubs private or shared?+
Always private. Every suite on Upgrade Suites has its own in-room or private-terrace water feature for your exclusive use.
