I'll start with the criticism... unfortunately, during our stay there was a terrible odour as a result of sewer gas coming into the bathroom because of faulty plumbing. We could see that there was no "trap" in the bathroom sink, letting the sewer gas back up through the pipes. This issue was not dealt with to our satisfaction, with the person sent to fix it bringing a stinky air freshener that only served to make perfumed sewer gas. Fortunately, we were able to do some minor fixes on our own to prevent some of the smell, but it persisted throughout our stay.
The place is one of a portfolio that "the office" (according to the person we talked with) owns or manages.
Visitors should know that (at least in November 2018), the apartment looks out onto a field of rubble due to the building next door being torn down. This looks like a long term project, and it does lower the charm of the location.
Now the good! This is a very well located apartment in Alfama. Lots of great restaurants and bars nearby, easy to get to from transit, and is perfect for 2 or 3 people (maybe 4, but the couch is pretty small and the cushions slide out of place while sitting on it). It has a great kitchen and TV and is freshly painted. The walk to it is not too steep, but expect a few flights of stairs to get up to it.
I hope the owners respond to this review and explain how they have fixed the smell. I'm also a bit annoyed because one person we talked to said they "thought it was fixed." After our stay, the email from the owner said "we're sorry this happened, no one had mentioned it before." Boo. Do better.
