The appartment is pretty good and very well located. Everything was as we expected and very clean, and Mateo sent us someone to open the door for us at our arrival.
The only thing is maybe we paid for what happened the weeks before in this appartment where previous guests organised a big party while you're not allowed to see anyone after 11 pm when you live in Madrid right now. We booked it for 9 people and we couldn't even stay in the living room without having the neighbours calling the police while we were only talking with barely no music at midnight. So the price is too expensive for an appartment you can't enjoy. Otherwise the rooms are good and it's great to have a nice bathroom in each of them. I would recommend this appartment 100% after the COVID pandemic/restrictions but be aware that the neighbours are pissed off (as they should) right now.
