A small, but comfy place to stay. Not large, but you have everything you need for a good trip to Lisbon. A perfect HQ with good location to visit all the city, 10-15 mins walk from the main markets, good connections via tram and buses, and the Uber takes you home after some nice Fado at nights for cheap.
The neighborhood was a big noisy at the evenings, but far bearable.
Nelson was kind and communicative, trying to react for all of our questions. Recommended host and apartment.
