We only met Gisele who was very nice and welcomed us even though we arrived later than expected.
The place is super clean and exactly as pictured. The location is very central so it’s quite noisy at night.
You’ll have to share the bathroom/toilets with all the people in the apartment so it might get busy sometimes as it was for us.
Other than that I recommend this place for a short stay in Madrid, it is a safe choice !
