Do not stay here!!! Someone entered our room without knocking when my partner was undressed. There was also a very loud siren/alarm that went off in our room every 20 minutes from 2am to 4.30am - this was on top of it being a very noisy room (in an old part of the hotel with zero sound insulation and beside a staircase where you can hear every footstep and toilet flush from upstairs). We were moved room at 4.30am because of the siren. The staff continued to suggest that the alarm was not their responsibility, saying it must have come from outside or our neighbouring room (despite us showing them videos proving otherwise). They are refusing to provide a refund for our sleepless night (not to mention the fact that someone walked into our room without knocking). The customer service level is worse than I have experienced in any hotel, including 3/4 star hotels. At each stage, the hotel has told us they would get back to us and then we have not heard from them.
