We stayed at Franz's place for 3 nights. The location of the apartment is great- close to the centre or the city.
Previous reviews stated that there was a bip card for public transport- just a heads up there isn't one. The apartment does the job for a reasonable price but is nothing special. If you want to do laundry the laundry is on level 25 - $1200 peso to wash and $1200 to dry- you will need $100 and $500 peso coins.
