The appartment is exactly as shown in the pictures with the big and sunny terrace definitely being the highlight. Great location - Quiet street but still only two blocks away from Avenida Santa Fe, one of the main traffic routes connecting Belgrano, Palermo and Recoleta. We did not see Marta herself but her housekeeper Maria was there whenever we needed her and Marta herself was very quick at responding to any inquiery we had. Aircondition works perfectly.
Only negative point was that the internet did not work twice during our 2 week stay because of unpaid bills. However, Maria and Marta took immediate action and the internet was fine again on the following day both times.
