Great spot in/near the Moorish quarter, a 10-15 min walk away from many of Lisbon's top attractions and restaurants. Absolutely terrific value with a friendly, responsive, and customer-service oriented host.
2 caveats: no AC. Not a problem for me, but may be for some. Also, it's on the street level of a very busy street. This was great for me as I live near downtown in my home city and love being so near all the action. But if you're the type that likes to withdraw to a silent hotel every evening, it may not be for you.
