This location is fabulous for all you want to do in Madrid. Minty Host made communication and check in very easy. Loved the prompt responses via WhatsApp. It was great to have the ability to drop our bags at their office before check in. The beds were comfy and the mini splits meant the unit was always a comfortable temperature for us.
On the negative side, there is some obvious maintenance needed in the apartment. The worst was the exposed wires in the light fixture above the second shower, so we did not feel safe using it. It's also important to know the place is very small. We did not intend to spend much time in the unit and were 3 adults and 2 small children, so it was fine for our purposes, but I can't imagine it for a much bigger group.
