It's a great place, and Cândida is a very hospitable and open person!
The location is perfect both if you're there to study at IST university (approx. 10-15 minutes to go) and if you're in Lisbon for sightseeing ("Alameda" station is approx. 5-10 minutes away).
The neighborhood is super nice and quiet during the night. The "Pingo Doce" supermarket is just around the corner.
The kitchen has everything you need, if you don't wanna spend money on restaurants you can easily cook there with much pleasure.
Would definitely stay there again! :)
