Clean apartment in a central location at a very competitive price for what you get (a lot of space and everything you need for longer stays).
There is a laundromat 2 minutes walk from the apartment if you need it, as well.
The low doorways were a bit challenging but this is to be expected in Portugal for a building from its era.
The communication was great and I enjoyed the stay a lot. One thing that puzzled me was the lack of heating which is advertised, but this is also something that barely any apartment in Lisbon has anyways and it was not really an issue for my stay.
Overall, I can really recommend staying at this apartment and would go again myself.
