I have been staying here for quite a while and I can say Enrique is just a wonderful person! First of first, he can speak English very well, which must be a plus for most potential tenants in the future. Second, he is friendly, helpful and ready to listen when you have a problem regarding the room and the flat. He always calls at the flat to check if anything is wrong. All in all, he is a reliable and a friendly landlord with whom you can expect to have nice relations.
About the flat, because it is just in the centre of Madrid, it is at an ideal place from which you can reach the most fundamental amenities such as stationary, bars, markets easily. Gran Vía, probably the most famous street of Madrid, is just a short walk away. The flat is nice inside, too. I especially liked the fully-equipped kitchen where you can prepare all kinds of food at your disposal with ease. Cleanliness is of high importance in the flat and one can always expect to see a salubrious flat ready for use at any time.
To sum up, the flat is at a very nice location; the landlord is a friendly person ready to help you with any problem you could encounter and therefore, I would recommend this flat to anyone that would like to stay in the centre of Madrid.
