This is the second time i stay at one of Ralf's flats, in both occations all was perfect from the reception, to the welcoming (water and fruit were at the apparment as a nice gesture). The flat is super clean, exactly as described. The wifi its fast, and the location couldnt be better, close to the tube, shops, restaurants at a trendy lively neighbourhood. Next time i travel to Argentina i wouldnt consider another place. I highly recommend to stay at Ralf's
