Room was clean and functional, tho somewhat Spartan.
Couldnt get the heater to work, and calls and messages to the management were not replied to. So I was and remained cold.
Shower was broken: boiling hot, no matter what I tried. Again, calls and messages were not responded to.
I had booked based on 'private bathroom' which admittedly does not say 'self-contained' but that is how I understood it. Bathroom however is across the corridor so not very 'private'. Anyone can access it.
But: you get what you pay for and location is conveniently close to Heathrow airport.
