First of all, the linen and bedding in general were spotless and very clean, and the staff were nice enough. Also, the breakfast wasn't bad. Therefore, I've given a 2-Star review.
However, the above factors are secondary to the primary objective of getting a good night's sleep!
In a nutshell:
-There is a loud sound EVERY few minutes which shakes the room. It is obviously the trains from the underground. The sounds die down at night and are now absolutely CONSTANT. YOU WILL NOT SLEEP past 6 or 7am. It's 7.56am as I write this (to post later).
-I can hear other guests walking around, plus can hear conversations very loudly and clearly. This "hotel" is basically a house with paper thin walls converted into a hotel.
-The WIFI is TERRIBLE! I have had one or two bars at best, and the signal continues to disappear for hours at a time.
-The room was slightly chilly last night; couldn't find a radiator or any heating switches. The bathroom is VERY COLD.
-You must hand in your key whenever you leave the hotel, though there is a 24 hour front desk.
