Marco and Sergio’s apartment was very clean, and looked exactly as depicted in the photos associated with the listing. They were very responsive (I.e. they responded quickly to messages). The apartment is in a hopping neighbourhood close to the action, while simultaneously being very quiet on the interior. They were accommodating when our flight arrived later than expected and allowed us to check in past midnight. That being said, they did request an additional 20 Euros when we arrived (adding up to 40 additional euros in total for our late arrival) which was not explicitly mentioned in the listing. Overall, lovely accommodations for our stay in Madrid.
