Its a great stay, i’d definitely recommend it. The flat is located right next to a supermarket and pharmacy and is about a 3 minute walk to Gran Via, all the while being located in a quiet plaza.
The flat had many amenities, including a washing machine, iron and cooking utensils. We were greeted with a bottle of wine in the fridge as well.
Paula had showed us around the flat, was very friendly and was willing to recommend areas around Madrid. Overall a great place.
