We did experienced some problems in the two weeks we stayed at this apartment. The hike up to the house is good to do for us three young girls (it was really pretty), but if you do have a disability we would not recommend a house inside the castle walls. We loved the big window and ate there allot because the dinning table was a bit small.
We had a situation with the downstairs neighbors (due to water damage) and it was hard to get Maria on the phone sometimes.
The problems we experienced did not took away the beautiful of lissabon and the taste of the pastel the Natas.
