Perfect! Myself and two friends stayed in Meli's apartment for 4 days. We had an amazing time. Meli is so lovely and helpful. She arranged for someone to meet us at the airport and take us straight to the apartment and made sure we had everything we needed. The apartment itself is very nice, modern, cosy and clean and in a fantastic location. We walked to the centre everyday which only took 10-15 minutes. And in the evening we got a taxi which cost around 7-8 Euros. I would definitely recommend Meli's apartment to anyone visiting Madrid.
