I stayed at Leo's appartment for a month. That was a very good experience. The place is an excellent location. It's close to everything, shops, supermarkets, la Plaza de Armas, two metro stations, etc. Leo was very attentive and brought me fresh towels and bed linen, sheets, etc every week. The internet has quite a good speed which was very important for me, since I work via Skype. The terrace is very big with a beautiful view.
Very recommended!
