Luisa was super responsive and helpful, her friend Karla was waiting for us in the appartment to welcome us, to show and told us all we needed to know. Beds were made and towels were left for us when we arrived. Luisa even booked a taxi for us when we left at 7 in the morning. The appartment was clean and very nice in the cutest neighbourhood and street. Be prepared to climb a bit to reach the building and appartment, it could be hard if you have heavy luggages, but it never was a problem for us.
I highly recommend Luisa and her appartment, it was perfect.
