The apartments location is really good, right in Centre of Madrid & for the price we got it was fine.
Unfortunately, the pictures, like with most Airbnb’s, are quite misleading concerning the true size of the apartment. It’s enough for 3 people but the picture definitely give a different image. Also the cleaning cost are really high. Other than that for the price we paid it was fine. The glass door to the bathroom is definitely something which might be weird, if you’re with people you don’t know that well. The glass door is not completely see through, thus it’s generally ok but like I said, wouldn’t recommend booking this with people you don’t know that well.
All in all, you get what you pay for and it’s right in the (touristic) center of Madrid.
