Amazing host, super attentitive, and the apartment was much bigger than we expected, very well stocked with helpful smaller touches like coffee machine, ironing board, etc. It's very trendy, well styled.
However, don't underestimate the 10-12 minute walk to either Alfama or the metro / bus stops as its quites steep hills. That walk is a minimum to get you anywhere. So after a long day of exploring Lisbon, it was a bit of a faff / effort to get back, get changed, and back out again. It did feel quite far out of town / main Lisbon areas.
Unfortunately, the smell from the bathroom really let this place down. It was fine when the windows were open but couldn't leave them open whilst we were out or overnight. In the morning, it would be quite overwhelming.
