I highly recommend Gabriela and Mike's apartment. It's quite modern (considering the building itself must be quite old) and spotlessly clean. Even the tap water is of good quality, doesn't have that chloride taste at all. Beds were really comfy and all the amenities you might need are there.
Gabriela and Mike are really friendly hosts, and all our communication was smooth.
They even left us a box of earplugs - just in case. We didn't need them at all, but it's characteristic of their hospitality.
A perfect stay!
