We loved the apartment - clean, well decorated, and conveniently located.
We stayed four nights and found the location to be perfect for exploring Lisbon. The 28 trolley runs directly in front of the apartment. (The 28 trolley is usually packed with tourists, so it is nice to have a stop near the apartment to take advantage of it in the mornings or evenings when it isn't so busy.) Of course, the trolley is a bit noisy, but the windows & buildings are built to minimize it.
We did make breakfast at home and the kitchen was equipped with everything we needed - even a juicer for oranges from the local market.
We highly recommend this apartment!
