I would not recommend anyone to book the single room. There was no window (which was not advertised) so there was no natural light at all. However, it did have a large hole in the wall, looking out onto the internal staircase. There was a metal grill over the hole, so it was secure, but it was completely open to all the noise of people coming and going at all times of the day and night, the banging of the front door, people going up and down the stairs, right outside the room. Also, during the night, every time someone used the light for the stairs, it lit up the bedroom, because all that covered the hole was a piece of paper. So if the noise doesn't wake you, the lighting up of your room will. Also there was no soundproofing at all, so everything could be heard inside the hotel too, including everyone's conversations, people in the bathroom, everything. It was impossible to sleep and the room was actually depressing.The staff were nice and the location is good, but no way does that make up for the very negative things about this stay. I recommend to avoid.
