Hotel SB Diagonal Zero 4 Sup
Barcelona, Spain · ★ 4.1 Exceptional B.Booking.com 8.2
Soak in your private in-room hot tub at this Barcelona hotel, wood-rimmed and built for two, steps from the bed.
The hot tub sits right there in your room at Hotel SB Diagonal Zero 4 Sup, ringed in warm wood, filling the space with steam and quiet. It's the kind of detail that changes a night: champagne chilling poolside, the bed visible beyond the rim, Barcelona held at arm's length. The bathroom is generous and lined in soft mosaic tile, with a rainfall shower and double sink. You're on the Diagonal, so the location is central and easy to move around from. Guests rate it 8.2 out of 10. The suites come in three flavours: Suite with Hot Tub, Suite with Spa Bath, and Deluxe Suite with Spa Bath, so you can pick the size and mood that suits you.

Questions, answered
Is the hot tub actually in the bedroom?+
Yes. It sits in the room with a wood-trimmed rim, visible from the bed and steps away from where you sleep.
What's the neighbourhood like?+
You're on the Diagonal, one of Barcelona's main avenues, so it's well-connected and easy to reach restaurants, shops, and transport. It's central without being in the Gothic Quarter crush.
Which neighbourhoods give you the best views from an in-room tub in Barcelona?+
The Eixample tends to deliver the most satisfying rooftop-adjacent and upper-floor options, with city grid views that reward a long soak. Properties like ME by Meliá Barcelona put you close enough to the action that you can hear the city, but high enough that you're properly above it.
Are the hot tubs and jacuzzis genuinely private, or shared with other guests?+
Every property we list has been verified for in-room, private use only. You won't be booking a suite and then discovering the tub is on a shared terrace.
