I had a short two night stay in the shared dorm at Selina.
Check in was easy and quick, the shared kitchen was clean and functional, and the wifi signal was good for online work.
The room was fairly basic though clean with a good shower. The main inconvenience is that the room got really hot at night, and as there seemed to be live music going on just outside the window both nights which was really loud so it wasn’t ideal to open the window.
Generally good value for a short central stay in the city.
