My 2 friends and I have just returned from Madrid having lived in this great apartment!
The apartment is very clean, modern and based in a great area. It comes with a number of appliances (dishwasher, washing machine, cooking hobs, microwave etc.) that would suit people that intended to spend more time indoors than we did. We were constantly exploring Madrid and the apartment is situated well for this with lots of bars, restaurants, Plaza Mayor and the Royal Palace of Madrid within 5-10 minutes walk.
In regards to communication, Raul was always available to help and ensured that our stay was as easy as possible.
