We had a great time in Lisbon. This place is really small, but our host warned us about this before we booked, and we like small places. There is a little hot plate, mini fridge, basic spices/salt/oil and pots and pans plus enough flatware, glassware, and silverware to cook for yourself. Probably couldn't make anything too extravagant but it was fine for eggs in the morning.
The one thing we didn't know that would have been nice to know ahead of time is that there is no wifi in this place. It wasn't too bad because most cafes and restaurants have wifi, but we found ourselves wanting to do research in order to make the next day's plan and not being able to.
That being said, our host gave us some great recommendations of what to do, including a great seafood restaurant called Ramiro, a place to get pasteis de nata (delicious custard tarts), and to visit Sintra, a beautiful town with castles and palaces that is a short train ride away. Overall, we loved our stay. Other than the wifi, it was a perfect little vacation.
