The Onsider - Luxury Penthouse Apartment with 3 Bedrooms, terrace and private pool, Barcelona Overview

The Onsider - Luxury Penthouse Apartment with 3 Bedrooms, terrace and private pool is a spacious Barcelona, Spain penthouse stay designed for groups who want privacy without leaving the city’s energy behind. Located on MERCE, 17, it suits travelers who prefer to come and go on their own schedule, especially families who need room to spread out. Guests typically highlight the practicality of having three bedrooms under one roof, which makes mornings easier when everyone isn’t sharing the same bathroom routine.

The standout is the terrace and private pool area, where you can cool off without competing for shared facilities. Reviews often mention how the outdoor space changes the pace of a trip: breakfast feels calmer, and evenings can be spent lingering after a day of sightseeing. Indoors, the apartment is air-conditioned for Barcelona’s warmer stretches, and the kitchen setup supports simple meals when you don’t want to dine out every night.

For downtime, the property also includes a hot tub/Jacuzzi and heated pool options, plus fitness facilities available for a surcharge if you want to keep a routine while traveling. If you’re traveling with pets, The Onsider is pet-friendly, which many guests appreciate when planning a longer stay.

In terms of nearby highlights, you’re within a short ride of Casa Batlló (about 2 km), La Pedrera (about 2 km), and Sagrada Família (about 3 km), so you can balance iconic architecture with restful time at home base. Best for families and pet-friendly road-trip groups who want a private outdoor setup in Barcelona rather than a standard hotel room.

Important information

A damage deposit of EUR 2000 is required. The host charges this 14 days before arrival. This will be collected by credit card. You should be reimbursed within 7 days of check-out. Your deposit will be refunded in full via credit card, subject to an inspection of the property.

Should You Book The Onsider - Luxury Penthouse Apartment with 3 Bedrooms, terrace and private pool?

Worth considering if you’re booking a group that values privacy and space, since a 3-bedroom penthouse with a terrace and private pool is a strong fit for staying in while still being close to major sights. It’s likely to feel like a premium, self-contained base, but you should confirm costs for add-ons like the fitness facilities and plan around the lack of on-site parking.

Best For

  • Groups of friends or multi-family travelers who want a private, apartment-style setup rather than shared hotel rooms
  • Travelers who prioritize in-room downtime with a terrace, private pool, and hot tub/Jacuzzi for a more exclusive stay

  • Pet owners who want to bring pets along, since pets are allowed

  • Travelers who need parking on-site, since parking is not available
  • Light sleepers or anyone sensitive to noise should be cautious, because the provided information doesn’t specify soundproofing or quietness
  • Travelers who want included fitness access, since fitness facilities are listed as a surcharge
