This apartment is located in the middle of a very popular area of Madrid with a thriving nightlife. It is very LOUD between the hours of 11pm and 3am every night (even weekdays). If you need somewhere quiet to sleep, I do not recommend this location.
The air conditioner is located in the living room, and the rest of the apartment is very HOT in the summer time.
The bathroom tub had mold on the shower curtain, and the place could use a thorough deep cleaning.
One of us left an envelope which contained 200eu and a debit card in the apartment, and the host confirmed that they found it. When we tried to collect it, the host came up with a bunch of excuses as to why they would not be returning it. I requested the money to be sent to me through the Airbnb support team, and I have yet to receive it yet. To say the least, I will not be returning and do not recommend this host.
