The location is great outside the super crowded area and right by the river where it's more flat. Nice to walk to Alcantara and other less touristy parts of Lisbon too.
It is a small apartment so probably better for just 1 person or 2 for a short stay where you're out and about most of the day. I spent almost a month here working remotely (great wifi) and Monica put in a desk for me which was really sweet.
The place could use a few more upgrades/supplies/storage to make for a better long term stay, especially if you like to cook as there is no official oven or stove, just 1 burner. There was also some confusion and miscommunication a few times when I asked to move dates around, etc and in the end I spent a lot more than I was hoping to for less than a month, but I know Monica really wanted to make my stay as comfortable as possible which I did appreciate.
