I needed somewhere to stay for 3 weeks while I studied Spanish. Aurora was really helpful when I was late and needed a lamp light replaced so I could study.
She’s right that the place is “pequeño” - i’ve had bedrooms that are bigger! - but it has a microwave, hob, bar fridge, and small bathroom with shower. It also has a desk and loads of cultery and cooking gear. There’s a laundromat fairly close by too.
If you want somewhere quiet as a base in the evenings it’s perfect (the room didn’t get much light in winter but I was usually out). Location is fantastic too - quiet with small supermarket nearby, and walking distance to most things in central Madrid. (I didn’t use the kitchen that much as so much was close).
