Excellent experience! Vanessa was very helpful and accommodating. She provided guide books and maps as well as answering many other questions we had about staying in Madrid.
They thought of everything when they stocked this apartment. They had all the supplies that we could have needed which not everyone thinks about. Cooking supplies, washing supplies, toiletries, etc. I can't thing of anything that they left out. Everything in the apartment worked well. The place was also very clean and the description was perfectly accurate (more than I expected).
The only thing I didn't like was the scratchy sheets.
I liked the location. It was nice that it wasn't on a main street but it was in walking distance of the Royal Palace, Sol, Opera, Gran Via, Plaza de Espana and of course the metro. I was told that the Mexican restaurant on the corner was the best in Madrid but didn't get a chance to try it.
Overall, I would stay there again.
