Super 👍🏻

10.0

Die Lage ist einfach perfekt wenn man mit dem City Bus durch Barcelona fahren will. Eine Haltestelle direkt vor dem Hotel

− 300€ für eine Nacht und dann nicht mal mit Frühstück. Das ist bitter

I expected better service. It started very good but at the end it’s gone.

6.0

Breakfast was perfect, lactation and room itself good.

− Crew do not respect „do not disturb” sign hanging on the door, they not care about env as they wrote on leaflet and you need to be careful about the info that you get on the desk cause someone other can cancel this without good reason

Maciej · PL · 2026-09-18

On the whole fairly good but a couple of things could be improved

7.0

Good facilities, on the whole fairly clean, helpful staff, good breakfast, and good layout for dining. The rooftop pool was spectacular, and the gym is very good for a hotel and is kept open.

− WiFi wasn't the best and disconnected a bit, my room wasn't cleaned one of the nights, few issues with my door and the card not working to open it, downstairs lobby ideally could be rearranged so seats are near charging ports.
