We stayed at Marta's place for a week and enjoyed it. The apartment is nice and clean, exactly as appears on the pictures. Windows are not on the street side, so it is very quiet. Location is great, it is 1 min from subway station; 1,2,3 trains have stop here which is very comfortable as you may use both local and express trains. It is walking distance from the Central park. There is a supermarket across the street.
Marta is great, she waited for us in the apartment when we arrived, even we were late and could not notify her about exact time we arrive.
