The house was very nice and clean. It's perfect if you have to stay for just a couple of days. It's at walking distance from Pastéis de Belem, which is the oldest bakery for Pastéis (traditional pastry).
The only problem is that the house is quite humid, but if you're visiting the city, you won't spend much time in the house.
It is amazing to see how you can make so much living space in a skinny house, great experience!
