Casa da Companhia vs The One Monumental Palace

Two Baixa addresses nine minutes apart on foot. Casa da Companhia if you want the all-rounder on pedestrian Rua das Flores with a rooftop pool and a rate that stays sensible; The One Monumental Palace if you want marble, a starred French dining room and the Avenida dos Aliados on the doorstep.

Casa da Companhia: The rooftop pool above the old townThe all-rounder

Casa da Companhia

The Porto hotel that balances address, pools, spa and price better than most, without being the best at any one of them.

€From about €165 a night

Choose Casa da Companhia if

  • First Porto trip
  • Walking everywhere
  • Central pool and spa
  • Couples

The catch

No Uber or Bolt to the door: only official taxis and licensed transfers may drive into the pedestrianised street, and the public car park is about 200 m away.

The One Monumental Palace: The 1923 facade on Avenida dos Aliados at nightThe grand one

The One Monumental Palace

The grand hotel on Porto's main avenue, a 1923 landmark with a starred dining room and a proper spa, where the address does the work.

€€From about €285 a night

Choose The One Monumental Palace if

  • First Porto trip
  • Walking everywhere
  • Grand-hotel weekends
  • Rainy-season spa days

The catch

Superior and Deluxe rooms are 29 square metres, which feels tight at the rate.

Good questions about Casa da Companhia vs The One Monumental Palace

Casa da Companhia or The One Monumental Palace?

Two Baixa addresses nine minutes apart on foot. Casa da Companhia if you want the all-rounder on pedestrian Rua das Flores with a rooftop pool and a rate that stays sensible; The One Monumental Palace if you want marble, a starred French dining room and the Avenida dos Aliados on the doorstep.

Is Casa da Companhia worth it?

The hotel in this edit that gives up the least: central, with two pools and a spa, and priced under the grand houses. It is the sensible choice rather than the memorable one. The most balanced set of numbers in the Porto edit: central, sensibly priced and with pools and a spa you would not expect at this rate. Nothing here is extreme, which is the point.

Does Casa da Companhia have a pool or a beach?

It has indoor and outdoor pools. There is no beach; the nearest is a drive away.

Is The One Monumental Palace worth it?

If you want to stay on Porto's main square in a building that has always been the grand one, this is the address. Pay for City Views, ask for the avenue side, and let the spa and Le Monument carry the evenings. The most central address in this edit and the most classically grand, a polished city hotel you leave every morning and return to for the spa and a starred dinner. Priced for the avenue and the building rather than for space in the rooms.

Does The One Monumental Palace have a pool or a beach?

It has an indoor pool. There is no beach; the nearest is a drive away.
