The apartment is very well located in the center of Madrid. We didn't hear the noise from the street and thanks to air conditioning, it was not too hot inside.
However we were really disappointed with the condition of the apartment. The bathroom smelled damp, the shower curtain was stained, there were marks on all the walls of the apartment, the fabric of the sofa was torn, the cupboard doors in the kitchen did not close... It really needs some updating.
There were also no essentials which are expected given the price per night (like coffee, shower gel...). It is also missing blinds that actually block the light in the bedrooms.
It wasn't the owner's fault, but the people in the next apartment were really loud.
To conclude, it was not good value for money. We expected better quality given the price. We do not recommend this apartment.
