Habitatio - Foz (Arantius) is a two level unit in a building that has been developed into many (~20?) rental units. The vibe is a bit like a hostel with a younger crowd, shared laundry*, etc. That being said the neighborhood is quiet as was the building. There were a few things I didn’t like here. I found the mattress to be uncomfortable (too firm). The bathroom is a bit awkward in that there is a low sloped ceiling over the sink. Using the mirror over the sink only works if you are, say, less than 4 feet tall. Finally there was one episode in which the code for entering the building (The only way to enter the building was via code; there was no physical key provided.) did not work. Fortunately there were two housekeepers already in process of getting that sorted out via phone when we arrived. Had that not been the case, it potentially could have been a significant problem.
All-in-all I would not stay here again. Upgrade the mattress though and I’d be back for the quiet nights and clothes dryer access.
*Note: You will need coins to operate the washer and dryer. 1 euro powers a washer (there are 2) for 2 hours. Same with the dryer. Laundry detergent was not present in the apartment but was delivered on request.
