Pedro's place is in a wonderful house – I would guess built in the 60s – located in the traditional neighborhood of Alvalade, a charming and coveted area of Lisbon.
The house is very close to the airport and within walking distance of trains (Roma-Areeiro station, access to Belém, Cascais, Sintra, Setúbal, and connections to nationwide trains), subway (Roma station, access to most of Lisbon) and several bus lines. There are plenty of cafés and restaurants nearby, as well as the Alvalade Market.
The place itself is very welcoming. I loved the kitchen, which has plenty of character. The bedroom I stayed in was spacious, with a comfortable mattress and plenty of storage (chest of drawers, wardrobe). The bathroom is also very roomy, with a full bath, toilet and sink. There is an additional toilet + sink room. Everything was extremely clean.
Pedro met me at the place on arrival and give me a thoughtful introduction to the facilities. He was very polite and thorough, and really made me feel at home.
I will definitely try to stay at Pedro's place next time I need accommodation in Lisbon.
