We had a lovely 3 days stay at Viento Duplex with terrace with H2M. The apartment is just on the outside ring of the old town, next to the restaurant area, but within 10 mins walk to major attractions since the old town is quite small. It is well equiped with fridge/ washing machine, air conditoning etc, Supermarkets are less than 5 mins away, a nice brunch restaurant called BrunchIT is just off the road. The Ataranzanas Central Market central market is at the end of the main road. Team at H2M was very helpful, checkin at central office at 6 Cordoba St was easy. If you have childrens, this duplex is ideal, my 6 years old son loved the arctic room, less ideal if you are not keen to climb stairs as there is no lift in the building. Good value for money for a city trip.
