Whatever you do - don't stay here! You might get some room on fourth floor with 66 steps to climb. Make sure you get a room with your own bathroom so that you don't have to use the one in the corridor. Do not believe the photos shown, in reality the room we stayed in was awful and I wish I could add the pictures I took during my stay. No isolation, we could hear the neighbours next door snoring as if they were inside our room! The bathroom spelled sewage!
I have rented more than 100 rooms over the last couple of years and this is not a good alternative for a stay in Brighton! I'm also disappointed with hotels.com, who should be more precise in their description of this alternative - misleading us made us "spoil" one of our holiday evenings/nights! It is the first time though I have been disappointed with hotels.com, but I consider this to be a 2nd class hostel, priced as a 3-4 star hotel. Try Grand Brighton instead!
