The location for the unit was perfect - however be aware that it's is at the top of four steep flights of stairs without an elevator, which was challenging for our elderly parents but doable for us. The unit was clean after the cleaning crew came, but was dirty when we arrived. Thankfully Margarida was very responsive and sent the cleaning crew over quickly so we didn't have to wait long. The property was as described and in a very great location; lots to do within walking distance.
There are some things that would've made the unit much more comfortable: a drying rack - the unit has a washing machine but no drying rack which is a problem for rainy winter when you can't hang clothes out in the rain to dry, power strips - there were not enough outlets to have a lamp on and a phone charging in the bedrooms, and repairing the broken doorknob/lock on the bathrooms would make it more comfortable, especially if staying with inlaws. But overall, a decent place to stay in Lisbon!
