We stayed for a week and every day discovered how wonderful our location was -- we walked to Reina Sofia, Retiro Park, Prada Museum and more. There are metro stations nearby. The apartment is on a side street but there are cafes that line an adjoining street so it can get noisy with the windows open. The bedroom is located towards the back of the apartment so we were able to get our sleep.
There were no misses, everything was as described and the apartment was roomy enough for my husband and myself. The kitchen is tiny but you could prepare a meal (we did). We would absolutely rent this place again.
