We had a wonderful stay in Madrid at this location. The apartment was well outfitted and conveniently located. Access was easy, while safe. Beds were comfy. Cute balconies looked out on the street. There is a hostel on the same street, so a little bit of late night noise, but not enough to keep me awake. The other bedroom was very quiet. Three very convenient grocery stores were within a 5-7 minute walk, as well as some great restaurants. Madrid is awesome and this was a delightful apartment as a home base for our experience.
The only small issue we had was that we were told to call once we landed and had our luggage so that they knew when we would arrive and would meet us. We had to use our own phones to call, even though we had WhatsApp or text, which would have been cheaper. When we called, we were told that they couldn't be there for an hour, though our drive only took 20 minutes. We parked ourselves at a small restaurant around the corner and had a coffee. After the 17 hour travel time, it would have been nice to get right in.
That said, the person who met us was very nice and knowledgeable. She gave us some great tips and kept in touch to make sure that we had transport back to the airport on departure. It really was such a great place to stay! We would use it again!
