Daniel's apt in Madrid is quite spacious compared to some of the locations we've stayed at in Europe, namely France.
The place was very clean, huge bathroom, a small partition divides the dining area from the sleeping area that houses a full bed. You will appreciate the vibrant cerulean blue accent wall. Fridge, range, and washer were all available, they all worked without complaints.
Upstairs you'll find another room with two twin beds if you need extra peace and quiet.
A decent location with plenty of bars, eateries, and markets around the neighborhood. You'll need to taxi or uber to the main plaza though but that's only a 15 min ride.
I actually prefer being a short distance away from all the tourist traps, seeing everyday spaniards going to and from work and just doing every day things is different than only seeing tourists.
