Hostel Inn Buenos Aires is located in the St. Telmo district of Buenos Aires within five minutes walk of the San Juan Subte underground train station. The building may be a little difficult to find, as the signage is subtle and not immediately evident from the street. When trying to find it, have the address handy -- it's number 820 -- and ring the buzzer to be let in when you find it. The hostel is affiliated with Hostels International and is friendly and well-managed.
Facilities include one computer with free internet, a small but relatively well-equipped kitchen, and free Spanish classes -- twice per week with other classes available on a paid basis.
The bunk beds are comfortable and the rooms are relatively large and airy. Unfortunately the downstairs rooms open off the common room, so they tend to be noisy. Earplugs are a good idea. There are ample bathrooms and hot showers within easy reach of the dorms. Towels, if needed, are available from reception.
Breakfast is included in the price and consists of a variety of breads, jam or creme de leche, and coffee. Quantities are more than ample and the quality is good. Officially it's available from 8 a.m. until 10 a.m. but the scheduling is relaxed so late-risers are unlikely to miss out.
All in all this hostel is a good place to stay. While the location is perhaps a little distant from the centre of town to be ideal, and the neighbourhood a little lacking in amenity, its proximity to the Subte makes up for this, as does the existence of an internet cafe opposite.
