I had a great stay at Carlos' place! The flat is very cozy and the location is very convenient for everyone who has a layover in Madrid and wants to have a place to sleep in between flights. The bed and the cover were very comfortable and the room and bathroom were both clean. There's hot water to shower and a very good water pressure! Carlos was very nice and forthcoming and generally a truly hospitable host. Our communication was very smooth and I really felt at home. Also the guinea pig Nina was adorable and added an even more "homey" feeling.
