Altido - this the worst host I've ever been in contact with. Before and after my reservation, I asked questions that were always ignored - example: do you have a high chair for my baby?. Instead, the host blackmailed me saying that he would only send the check-in details if I send detailed info about the 8 guests that were planning to stay there. Eventhough I had shared my personal details with them and said that I would need more time to get all the details (yes, I do not know the ID numbers of my friends by heart). Not to mention that this is not legally required when the guests are Portuguese...Finally, and of course the worst part, the host cancelled the reservation a few hours before the check-in for a NYE stay! They didn't bother to call, just a plain message in Airbnb wishing me luck to find a new house for 8 people 3 days before NYE.... My advice is to avoid at all costs staying with Altido in one of their houses.
