I stayed here for 3 days and loved being in the area around the castle.
I ate in the restaurant downstairs on my first night and the staff and the food were lovely.
I see that some people have mentioned noise - it’s a popular area with plenty of people around, so there is some noise but I rather liked it! Sometimes there was music and chatter until about 11pm but I just enjoyed that with a glass of wine or beer upstairs and it didn’t stop me sleeping!
The shower does overflow onto the bathroom floor (which I’ve mentioned to Casas) but it’s a lovely shower and the towels were great.
The bed was comfy and the kitchen area was good too, with enough things to cook with etc. I think there was a coffee machine but it made no sense to me so I didn’t use it 🤣
I walked miles and this is a great base to explore Lisbon from - plenty of places to eat and a big Pingo Doce supermarket about 10 minutes walk away.
It is a hilly area, with lots of steps so make sure you’ve got comfy, non slip shoes and enjoy your stay!
