On arrival Nacho's friend met us. Two things went wrong: 1) she asked for a 150-euro deposit in cash (which Nacho never mentioned) and 2) the apartment is a 4 floor walk-up with 70 stairs each way. I just had knee surgery, and we have 2 small kids, so the stairs were a problem. I contacted Air B N B about the deposit and they said it was against their regulations to demand a cash deposit, so if you stay here please know you don't need to pay it. Otherwise the apartment was pretty nice though there was a dog in the building who barked at all hours, waking us from 3, 4, 5 AM.
