The appartment is well located on downtown, 5 minutes walking from many coffees, stores and subway.
Jimmy answers very fast and he is very kind. He provided many recommendations for our trip, helped us on the arrival and left some details such as a wine in the appartment. The shower was very nice and the appartment has many facilities (I even was able to wash the cloth).
Only thing is the stairs to access with lugagge, but this is very common all over Lisbon.
We would totally recommend you to stay on Jimmy's appartment, you will be able to nicely enjoy Lisbon.
