The location is incredible. All of the major sites in Madrid are within walking distance. The wifi speed is excellent. The unit is up 4 flights of stairs in a fairly noisy building with many residents. You will be sharing the space with potentially 8 people and 1 kitchen and bathroom, so that can get congested and messy. The trash was overflowing for multiple days, the water heater for the shower is temperamental, and the soap in the bathroom was mostly empty. The beds are uncomfortable, and there were no blankets leading us to wear coats while sleeping. Again, the location is pretty hard to beat, so if you’re under the age of forty and are up for a hostel-like environment, go for it.
