Sergio coordinated with me around arrival times. We didn't know the apartment number, but after being outside for a bit and calling/getting voicemail, he used the intercom to let us in. He met us in the apartment (5th floor walk up), oriented us to the space and left.

The current layout of the place is different from the photos and possibly changed the feel from cozy to small. Part of it was timing; there was a lot of laundry drying in the living space that took up a lot of room. Also, the small desk in the photo has been replaced by another shelving unit, which means that there is one less place to sit things down.

We used the kitchen, and that worked well. There was a stovetop cafetiere to make coffee. The bathroom was small but had good water pressure. I challenge anyone to successfully shower without hitting the water temperature/handle by accident.

The wi-fi is very bad as it is right now. My main frustration with the place, since we would use it to research excursions etc.

The neighborhood is great for Indian food. There's a whole street of it nearby. It felt like Brick Lane in London. You are within walking distance of the commuter-type train station at Atocha, which was how we got to the apartment. The local metro stop is closer, but had connections etc from the airport. For leaving, we took an Uber, and they sort of struggled to find the place.

Overall, an affordable home base for your Madrid adventures. I would give 3.5 stars, but will round up to 4. It was really convenient for me, and although small, the price is very affordable.
