I unfortunately can't say I had a particularly nice experience when staying at Carlos'. When arriving around the agreed time I had alot of difficulty finding the apartment, as only the number of the building was provided and the name on the door was rather different from the one visible in the correspondance. After trying to call Carlos numerous times (11) my phone died making me have to walk back all the way to the airport to recharge. Granted that a dead phone is my own fault, it would've been nice if Carlos just answer on the first couple of tries and all this would've been a different story.
I did in the end find the appartment with the help of Carlos, but ultimately can't say I enjoyed it very much.
