What a great experience we had staying in Ago's beautiful apartment. It is ideally situated in the heart of San Telmo, a district bristling with history, restaurants, culture, bars, markets and tango. In fact it is on Defensa, the street that holds BA's famous market every Sunday. The plus is that the market and all its sounds are there on your doorstep. Just don't expect a quiet Sunday lying in after 10!
Ago herself is a delightful host. She was always reachable and quickly got back to us when we had an issue with water appearing on the kitchen floor. She is always incredibly friendly and supportive to the point that she let us arrive a day early (I'd made a mistake with the arrival date). Sadly, on the day of our departure we had our bags stolen whilst waiting for the bus to the airport at the nearby Paseo Colon (BA is generally a very safe city but there are expert teams of thieves operating so be aware - we were hit by a team of four who threw an excrement like substance on my wife to distract us before engaging each of us separately whilst the third and fourth team members took our bags. Be extra cautious when laden with bags etc.). Having had my wife's passport stolen along with her purse, phone, etc. Ago and her boyfriend Pablo very kindly came to our aid, collected us, helped us cancel our credit cards, took us to the police station to make our report and let stay an extra two nights for free as we had to wait until the Monday to get to the embassy and arrange new travel documents.
We couldn't have been more positive about Ago's apartment as it was but without her help we would have been truly stuck. Unless you want to be elsewhere, just book it!! :-)
