The apartment is perfect for up to 4 people (the beds are just big enough for two). The location is amazing and it is fairly clean. The kitchen is not fully equipped, but you don‘t really need that anyway when you live so central. The bathroom however was well equipped, including shampoo and shower gel.
Raul was very communicative and responsive to our questions. The check-in was easy and just as described.
The door handle to the little terrace was broken, but the terrace is only accesible from within the building itself, so no outsiders could get to it. Raul ensured us that it gets fixed on the 30.05.22 (the day we left). Even though nothing bad happened, it still made us feel a bit unsafe and I hope that the door is fixed now.
One of the ACs also didn‘t work, but Raul told me he will check it out after our stay.
All in all, this is a good place to stay in Madrid.
