We had a great time in Guillermo’s place. Just as described. The place is well-located & quiet. Fairly clean, a bit dusty but not bothersome. You have everything you need (laundry machine, dishwasher etc.). We were able to discover Madrid by foot easily. For the check-in, we were running late because of our flight being delayed but Antonio welcomed us & was very nice. Communication with Guillermo & Antonio was smooth. Fave spots close to Airbnb was Cafe Federal and Mica Restobar (highly recommend both). Muchas gracias!
