Absolutely terrible. Firstly , it's not separate apartment as I expected , its one big apartment with several rooms which they call studios, rooms are quite small , no kettle, no iron and no proper toiletries , beds and pillow were the worst and if you are 180cm or taller then you feets will be hanging from bed because the length of the bed is small and it's not suitable for couples as they are two single bed adjoined to each other. sofa bed is just a joke, I suggest not to use it as it can give you very bad back pain.
I read the reviews before so honestly I was not expecting anything good and I had to book last minute only for 1 night because I had no much options available near atocha but will never come back here again.
