The space is clean, nicely decorated, and allows access to the whole apartment should you want it, including a washer, dryer, and kitchen. Bathroom could be shared with another guest and Alex, but I was the only one staying there for the three nights I was around.
I mentioned through the app that my train would be arriving much earlier than the check-in time and got messages from both hosts saying they could let me in early. I arranged a time with Vitor, and then when I got there almost an hour earlier than that because my phone was in the wrong time zone, Alex quickly showed up instead. Very accommodating and it's highly appreciated.
The description isn't joking about what a hilly area it is. I walk a lot and it was still some effort getting my bags to the room, even in winter. Still, walking distance to Santa Apolónia station, where my train came in and there's a subway line; a bit of a further walk to Rossio, where you can catch a direct train to Sintra; in the Alfama area with some tourist sites like the famous lookouts; other tourist sites were a half hour walk or easily accessible by transit.
Great value and I'd be happy to return!
