Luís is very kind and caring, nothing is too much for him. He will help you with any kind of question you have and has a lot of good tips to explore the city. The house is clean, comfortable, however it is quite far from the city center so this means that most probably you are going to use the metro or Uber a lot. I recommend staying at Luís' place if you are alone or a couple and you want to experience Lisbon on a calm pace. If however you want to be in the middle of the busy city life this place might not be it for you. For me it was exactly what I was looking for, for a stay of 4 days
