We loved our stay in this charming apt.! It is a really great place for a short stay - clean, modern, with very responsive staff. All of our questions were promptly answered via email, air bnb, and over the phone. Our check in and check out experience was also great, and very punctual.

We found the apartment to be much nicer than the photos, with the space with 2 sofas (one of which is a sofa bed that pulls out), being larger than it seemed online. The apartment is a split level, and the rooftop terrace has 2 areas - one dining area indoors (which you can open up) and another large outdoors area with sun loungers. We would recommend this place for either 2 guests or a couple and a guest.
We really loved the welcome package of wine and cheese, etc. especially after a long day of driving and the kitchen is surprisingly well stocked with all kinds of pans and utensils and kitchen accessories, if you're so inclined to use them.
Most old Lisbon flats in the centre are very noisy, but this one was very quiet, despite being central. Also despite being in Alfama, it is up one of the shorter hills of the area, so the journey with a suitcase up to the apartment is not as painful as it could be.
Lastly, this has been mentioned before in other reviews but - the ceilings are very low and the steps are steep, so if you are very tall or are unable to climb stairs (or have large heavy bags), this would be something to consider!
