We stayed at Daniel's apartment for 4 nights and really enjoyed it! He was prompt to reply and he was very understanding when our train from Porto was delayed by an hour and check in was very easy since he lives in the same building.
The entire place was very large for the two of us and we really liked that we could pull the couch out into a bed so we could lay down and watch TV to unwind after a long day of exploring Lisbon. Fully equipped kitchen and laundry room had detergent which came in very handy.
Great location and excellent value. Highly recommend!
