We stayed at Andres' apartment for 3 nights and had an amazing time. The apartment is perfectly located and has everything you need.
It's in a calm small street, but only 5 min walk from all the restaurants and tourist places.
The communication and the check-in with Andres' friend was so easy and nice, that we had a perfect start. There were maps and recommendations in the apartment, which we didn't use as we love to explore, but it's very nice to know it's there.
The bed is comfy, the coffee is delicious, the bathroom seems to be very new...and the wifi is fast enough to watch netflix, etc.
Highly recommended! :)
