A wide range of accommodation possibilities are available in Buenos Aires and the rest of the country, from student hostels to homey bed and breakfasts to trendy boutique hotels in the city to luxurious palaces and modern five-star hotels. There are also many beautiful lake-side lodges in Patagonia, and fabulous regional farms estancias outside the cities.
Many vacation cabañas cabins or weekend houses are available for short-term rent directly from the owners in the mountains, seaside, and in rural areas. Drive around and look for signs saying alquiler "rental", or check the classified section of any major newspaper.
Bear in mind that except in the 5-star hotels, usually the rooms are not as large as in hotels around the world.
