Online check-in introduced unnecessary difficulties. Lights (and electricity) did not work.
I learned after I booked - paid for and confirmed - my stay that there was a mandatory online check in process. At that point, I was already in Spain. That process required confirming my phone number. I had left my primary phone in a repair store in the US - I could not confirm that phone number. I brought a cheap american phone to Spain for WiFi, but even after buying a pre-paid spanish SIM card, I could not text to confirm that number either (apparently spanish and american texts are on different bands). This was resolved by emailing the reservation email from a previous hotel wifi, but was sort of terrifying, and took a lot of time / worry.
When I got to le palecete and used the keycafe check-in locker, I got a keyfob without a card. I tried emailing from the lobby wifi, and that did not get a response in the thirty minutes while i downloaded skype to call. They were very helpful on the phone in getting me another keycard, and I got into the apartment.
Once I got into the apartment, none of the lights nor sockets worked. The breaker panel was open - so someone else had had this problem before, but flipping the switches did nothing. I was out of battery/power to call again, and just went to sleep.
There were no checkout instructions.
The room itself was beautiful, in a perfect location, walkable from everything.
