I've stayed at Marco's place for the past few days, and it was a total nightmare. The room was literally colder than it was outside. I asked about a heater, he said there are none. At first, I didn't make a fuss about it. Then I wanted to shower, but the water was freezing cold. I wrote to him about it, he video called me and told me the water heater is out of battery and asked ME to go buy new batteries. He said he'd cover the cost of the batteries, and so I went out in a city which I've never been to before, looking for batteries (because he said he'd cover the cost). Mind you, they were large batteries, not the kind you can find at every local store. So I buy the batteries eventually, come back home, and at this point, I reallyyy need a shower because I just came back from the beach, and I was sweaty. I put on the batteries, and they don't work. I call him, explaining the situation. All he says is that he feels bad for me and that it is unfortunate. Oh, and also he didn't give me the money for the batteries.
But just wait. It's not over yet. The whole set-up of his airbnb is a bit shady. The first thing he told me when I came to his place is that the person that lives right next door from the room he rents does not like the fact that Marco rents his room, and so I shouldn't tell him I'm an Airbnb customer Eventually, someone comes home and asks me, mind you Marco is not at home at this point, and I tell him I'm Marco's friend, because that's what Marco told me to say! I was scared that this other person might create problems, so I had to go with the story I was presented. The other person clearly does not believe me, it's obvious, but he doesn't say anything and goes to his room.
Overall, I would not recommend his place. Especially during winter, when the room is super fricking cold. I come from Vienna, where it is on average around 10 degrees colder than Lisbon, and I was freezing in the room. On another note, Marco is responsive, but he doesn't solve problems. I've worked in customer service before, and I know in the corporate world you get fired for dealing with customers the way Marco does.
