Stayed here over Christmas 2016 with my girlfriend (Argentinian).

LOCATION: The flat is not right in the centre of San Telmo (e.g. by the S.T. Market / Plaza Dorrego) like another AirBnB place I have stayed in previously, but is certainly within a reasonable walking distance, so a great location because it is both near enough to central S.T. but also only 1 street over from Avenue 9 De Julio - which outweighs the walk to central ST. For me, there isn't so much to do in S.T. that it is all you would want to visit, and being next to 9 De Julio means the rest of the city is on your doorstep. For those that don't know - it is the main street for catching buses or the subway all over the city. So if you have your sights set on seeing more of the city than just S.T. this is actually a very good location. You can also find most of the ATMs on 9 De Julio (intersection 9 Julio with Carlos Calvo / or 9 Julio with Belgrano), with only 1 other ATM in central S.T. itself (which didn't work for me). So it is a good choice if you want to be near enough to S.T. but also branch out and be able to get to / see (and get cash out to pay for) a visit that includes the rest of the city. Many machines only give $2,000 pesos per day so you may need to visit more than once if planning to pay by cash for things.

THE FLAT: The flat has a few wobbly floorboards etc. - so over-demanding people expecting unrealistic 5 star hotel perfection from a charming old apartment block in B.A. might be able to find faults... but for those looking to "keep it real" and have a real AirBnB experience (a taste of how locals live), I'd have no problem in recommending Ura's place. People say "hola" to you in passing and you see and smell people sitting down to dinner. The flat itself is on the end of the block though so you don't feel too crowded in by the neighbours.

URA: Ura herself is communicative and responds quickly to messages, even if she isn't physically around herself at the time - so no concerns there. She was helpful & accommodated an early check in for me by arranging with the cleaner that I could drop my bags and then get coffee / breakfast in San Telmo while she finished cleaning.
