Isabel's place was great! it's a perfect jumping off point to all the best places, and I loved being so close to the parks to take a run or get some fresh air.
the wifi is amazing, if you work and travel, I had absolutely zero issues my whole stay.
Her place on the whole is pretty quiet and insulated from the street noise because the window faces a courtyard. I could usually work just fine and sleep well, even when Buenos Aires had the mother of all parties during the World Cup :)
it's pretty equipped with a nice kitchen and it's more spacious than it appears. I would for sure come back!
