I have to say that this was the messiest arrival by far, and I've been renting flats with Airbnb for a long time.
The day before we came, I asked to Miguel whether it would be possible to check-in around 12 a.m. Not possible, but understandable if there were some guests before us. Miguel told me that we would meet his assistant at 1.30 p.m. and gave me his phone number. When I called the assistant to check with him if he would be there at 1.30, he told me that he was on holiday. I don't even understand how I got the phone number of someone who obviously wouldn't be available.
After a quick call to Miguel, he told me that another assistant would meet us at 1.30 (but didn't give me any phone number).
1.30, no one is there... 1.45, I call Miguel, one more time: "This will not be my assistant, but my cleaning lady, she'll be here soon, but she doesn't speak english very well".
2.00 p.m., the cleaning lady is coming. The poor lady was clearly running from flats to flats. And bad luck, she was speaking english as good as I was speaking portuguese: not at all, but I can't complain about that, she's not supposed to deal with tourists.
With a subtle conversation mixing french and spanish, I managed to understand that the flat wasn't ready yet, and that we would have to wait for up to an hour and a half. To be sure that we understood well, she called Miguel, who explained me this. Now, you need to know that sometimes, people need to get some rest after getting up early to take a flight. If we agreed to check-in at a definite hour, the best is to deliver the flat at that time. Fortunately, the beds were already done, so we got some rest while the cleaning lady was working.
To me, this is one of those flats where you barely have contacts with the host, as their ultimate goal is to rent and make the most money of it. Too bad I've had so many nice experiences with Airbnb before. Miguel, you definitely need to order your things up.
That being said, the flat is fine (except for the corridor to access it, which smells like pee, thanks to the dog of the neighbour) and very well located. Basically, you can do whatever you want from there: go for a walk in Lisbon, take the train to come from/go to the airport, or to Belém.
