Adorable apartment in a great location! One block from vegetarian restaurants and a supermarket, super close to the metro. Very quiet with the windows closed or open them to enjoy the tree in front of the bedroom. It's a good amount of space for an extended stay, and the kitchen had a French press and olive oil - you can easily make your own breakfast.
I had a slight issue accessing the apartment one afternoon when the batteries in the door died. If something like that happens, be prepared to be the point person - go get the key, stay home for the cleaning lady to replace the batteries, etc. This caused me to miss part of my conference, which was unfortunate. But the chances that it will happen to you are very small.
