We loved staying at Diogo's apartment. It felt like home. It was very clean and comfy and we appreciated the welcome gift. There were a few items in the fridge to get you started if you hadn't had a chance to go shopping. We didn't use the dishwasher, preferring to wash by hand, but we did use the washing machine and outside washing line out the window (3rd & top floor). The place was quiet and I never heard any traffic. There was a take out BBQ place (yum) 2-3 mins walk in one direction (& also a pizza place) and the metro (Encarnacao) 3 mins in the other direction.
When finding the place your GPS may stop you at the wrong building. Get out and look at the building numbers or use google maps in walking mode. It is the top (3rd) floor apartment and then the right hand door.
