My experience staying at Marco's house was excellent. He was super welcoming and knew a lot about the city. Marco's place was in a GREAT location, near tons of restaurants and local shops. There's a great little market that opens up right down the street on the weekends (at least while I was there), and I highly recommend to grab some cheap food and good quality souvenirs. Anyway, his place was also very clean, well kept, spacious, super safe (it has a doorman and limited entrances to the building), had warm water, and was well worth the price. Plus, Marco is a really friendly guy which made staying there even more comfortable. I highly recommend staying at Marco's!
