Iacy was a pleasure to deal with - she responded quickly to my messages and made things very easy for me and even left us bottles of water in the fridge. The astonishment is very centrally located, about two blocks from the beach, with a doorman (who we got the key from when we first arrived) very safe, within a ten minute walk of the metro, and has a few usa format power outlets.
There were only two issues with our stay: there were a few fruit flies buzzing around and a smell that alternated between cat urine and fish tended to hang around the apartment when we returned to it at night. The other conveniences of the apartment made up for this though!
