The apartment is located right on the edge of Alfama with a view of the port, so it is a great location, accessible to everything you would like to walk to (uphill!).
It is a beautiful place, but not without its quirks. Although there are several doors to open in the main living area that cause a wonderful breeze, the bedroom is in the interior without much airflow at all, so a fan would be a nice addition. The bathroom has a door, but it does not close all the way and has a lattice wood design, so you can see through it. It's not very private so make sure you are close with your travel partner:)
We never communicated with the owner, but with a couple other people that were house managers (though we didn't meet them either). Check in was smooth anyway and all in all a good value for a pleasant stay. Eat at Trigo Latino downstairs!
