It was a fine nineteenth century building in the same state of repair as most in San Telmo. The paint was flaking from the shutters, the stonework had fallen from the balustrades; the stucco was criss-crossed with graffiti.

The sign outside called it a hotel, the WiFi code called it a hostel. More than anything, though, it recalled the cheaper guesthouses of Bangkok.

The room was hot and airless. The fan did not so much cool the air as swish it about, and made a noise like the treadmill at the gym. The walls were dirty, the floorboards were splintering, the French doors had swelled too much to shut. There was the inevitable dead cockroach in the corner, as ubiquitous in hotels at this level as Molton Brown toiletries at the top end. It was there when I arrived, it was there when I left five days later, and it is probably still there now.

There was a sort of a patio linking the room to the bathroom, but it had a high wall blocking the view to anything but rusting tin sheets, broken windows and ferns growing up the inside wall. If I stood on a chair, though, I could look over at the place where they slung the broken furniture.

San Telmo is a characterful neighbourhood, the oldest in Buenos Aires. It was a poor barrio, centred upon a Jesuit mission, until 1767 when the Spanish drove the Jesuits out. It briefly went upmarket in the mid-nineteenth century, but a yellow fever epidemic put a stop to that. The rich left and their empty homes were carved into tenements and filled with immigrants fresh off the boats from Europe. Artists later moved in among them and lent the barrio the bohemian air it retains.

There was neither the money nor the mindset to tear down the old buildings and replace them with new, to extend or to bring into line with each ephemeral fashion, so everything stayed much as it was, photogenically decaying.

In the mornings, the smell of strong coffee and freshly-baked empanadas hangs in the air all over the barrio; in the evenings, the smoke converges from the many parrillas* as thick slabs of prime beef sizzle on grills. The convenience stores stay open late and do business through bars on the doors. The jobless sit listlessly in doorways; some sell odds and ends laid out on blankets.

There are rusting tram tracks up Calle Estados Unidos, although trams have not run on them for half a century. Dozens of Quilmes bottle tops have been trodden between the cobblestones outside the bars.

I assumed that the cars parked up the street had been abandoned years before, until one of them grumbled past my hotel. It was as if all the cars from all the scrapyards of Buenos Aires had come spontaneously to life to roam the city’s streets. One was missing a bonnet, another a windscreen, and a few seemed to have been in the sort of accidents which make the front page of the newspaper, yet remained in everyday use.

Mercado San Telmo is outwardly unchanged since the last years of the nineteenth century when the barrio’s European immigrants went there to buy cheeses and hams from back home. It takes up the whole of the block between Estados Unidos and Carlos Calvo, opening out in the middle to an attractive wrought-iron and glass atrium.

There are hole-in-the-wall stalls selling beer and choripanes, baguettes toasted on the grill and stuffed with chorizo and slathered with chimichurri sauce**; but they seem, sadly, to be getting edged out by shiny coffee stands which could be anywhere from Washington to Wellington, from Cape Town to Cape Cod.

There are still butchers and greengrocers, as there have been for going on 120 years, but much of the market is now given over to antiques: to tinplate toy cars, brass letterboxes, old tango posters, military uniforms, radios, typewriters, and telephones. The antique shops continue down the lower end of Carlos Calvo and round the corner along Calle Defensa, interspersed with wine merchants, bodegas and design shops, all the way to Plaza Dorrega where the world-famous antiques fair, Feria de San Telmo, bustles every Sunday morning.

A block to the south, there are two good galleries side-by-side, Museo de Arte Moderno and Museo de Arte Contemporáneo, then the gentrified end of San Telmo fades into the dangerous edges of La Boca.
