Byron and Gerard are such nice, friendly, welcoming and reliable persons! We spent 4 nights in their apartment during Mad Cool Festival 2017 and had a really good time there! Description of the flat is precise and the two even bought us a bottle of wine as a welcoming gift, gave us a heartwarming welcome includung "Felicidaded Laura y Kon" on a sign and gave us a fridge magnet of madrid for goodbye :)
We also had the chance to park our luggage at gerards other apartment, so we had the opportunity to explore madrid on our last day, as we checked out at noon and our flight left at 8 pm.
So nice, we would definetly stay there again!
Also, the flat was perfectly clean etc.
Best greetings from germany!!
