Beto's place was exactly what I needed. I was flying into Lisbon airport from the Azores and had an overnight stay to catch an early bus ride in Oriente the following morning. I booked Beto's room for location (walking distance from airport terminal--walk on right-hand side sidewalk out of airport and head to Olivais Sur using his map) and the price.
The room at Beto's is at one end of his apartment. It's small, basic and super clean, plus rigged out with wifi, TV, Alentejo wine, a bowl full of fresh fruit, chocolate bars and water. For a guy like me, that's really all I need (and the fruit was a treat).
Beto is a former firefighter and I had fun discussing local politics with him. He really goes out of his way to make you feel comfortable in his pad. Full of little details, he even gave me a fridge magnet as a souvenir.
Next morning: after making an espresso for both of us, Beto drove me to the bus station before he headed to work. Saved me hauling my luggage down to Oriente. That's the kind of hospitality you will get from Beto. I speak Portuguese, so it may have helped. But I'm sure he would make the effort with others. Very recommended.
