Carlos appartment is located in a building that reminds a hotel, with a reception. It is not big but is extremely clean, just renovated, with all required appliances, super comfy bed, powerful airco, etc. Carlos was very fast to respond to the messages and flexible with regards to check in and out. Location of the flat is another benefit: it is just 30 min away from airport due to underground train station, vibrant Chueca is close too and many restaurants are just at the footsteps. The flat is also quiet.
