When we got a taxi from the airport and ended up outside the apartment we initially thought it might be concerning as the neighborhood looked a little rough- lots of guys hanging outside nearby bars.
it is absolutely fine and safe and actually a really the most interesting area the old quarter. it looks much sharper by day with the shops plan and there are some good restaurants nearby and plenty to see with a metro station 4 minutes away if that. supermarket 50 meters away.
Inigo was the perfect host. prompt responses and eventually when we wanted to organize a cab back to the airport ; let us leave our bags until the next guests checked in to give us the day to explore again and negotiated a reasonable fee to take us himself. highly recommended for an interesting stay in a very clean simple adequate apartment with lots of space and a good kitchen and bathroom.
