Raul is a great host and I really liked the apartment. It is downtown, which might not be everyone's taste but the building has lovely staff, is located next to everything you would need (station, supermarket, restaurants, pharmacy, loys of cabs in the street etc.) and is a little less hectic than Bella Vista. The apartment is a little oasis, spotlessly clean, with a TV, landline, super-fast internet and comfortable big bed. It cost 15,000 - 17,000 in a cab to the airport but Raul can also book your transport with TRANSVIP for much less. There is a lot of local info and guides for your use in the living room. It's also a few blocks to Plaza des Armes, which has free local guides throughout the day: it is a great way to orient yourself in the city. This spot is highly recommended!
