Teresa's apartment is located in the heart of many great restaurants, shops and attractions. The balcony overlooks a busy street however, the glass patio doors are sound proof and we heard nothing from the street while sleeping. The apartment is very clean and well organized. Teresa was very responsive to any questions and knows a great deal about the area. We only had 3 nights in Madrid but I would recommend more. There is so much to see and do in the beautiful city. We loved staying there and will definitely return.
