That's true, I meant to add in my review that Hernan graciously (and appropriately) offered a partial refund which I accepted. I certainly appreciate that. But as Hernan well knows I took the key with me as I departed because on the same day that the wi-fi signal was lost the electronic button that opens the main door to the street was damaged by vandalism and the only way to leave the building was with a key. So obviously I had to have the key in hand as I left. Much like the wi-fi situation I explained this to Hernan who was disinterested in understanding and accepting the situation. Needless to say I remained in contact with Hernan on the subject of the keys and returned them to him in the manner and at the time that he requested. So his implication that I kept the keys is disingenuous at best.
And again, my issue wasn't so much the lack of wi-fi, it was that Hernan's guests apparently use signal from some other unit that Hernan cannot access. I feel like the amenities that a host offers the guests should be under the control of the host, not some random third party. And as I mentioned in the review this sort of haphazard approach is evidenced throughout the apartment in details large and small. Which is obviously a primary reason why I declined his offer of a different apartment. I'd seen how he operates and opted for something different.
Hernan seemed like a nice fellow. It's too bad things aren't as cordial as they might be but I suppose that happens once in a while.
