Elsa and her family were, by far, the most responsive and engaged hosts I’ve ever stayed with (and I think I’ve stayed at 25+ airbnbs). They went absolutely out of their way to make our stay as comfortable as possible. When we couldn’t figure out how the washer/dryer worked, they did our laundry for us (including folding it!). We weren’t comfortable with the gas based space heater, and they brought over an electric one for us. It was really above and beyond how much they tried to help!
One thing I will say about Elsa’s place and about staying in Lisbon: it’s an old city! I honestly wasn’t ready for this - do your research. It’s very common for places to not have central heating, for the building to be creaky (if your baby is crying, all the neighbors will hear you :D), for all the sidewalks to be cobblestone (aka not stroller friendly - bring a carrier!). If you want a different experience, make sure you look for it explicitly in your airbnb search.
