We stayed in room 101. All 10x rooms are "cells" with no window for the bedroom, but only a small window on 1. floor, a small room with a sofa. Thus the rooms are quite dark and difficult to get fresh air into, which makes them uncomfortable to sleep in (aircondition is available, but has virtually no effect as it is mounted on the 1. floor).
We paid 200/170 Euro for a Saturday & Sunday night, wich is almost 2x the price of other Pousadas.
The restaurant is quite good with a phantastic view of the bay area. Meals are according to 4* - no better no worse. Service is excellent and the staff is really committed to do a good job.
If you make a reservation make sure you get a room on the 2. floor, the main building, with a window to the harbour.
No WiFi available. Parking is in the castle but there are some stairs/a long entrance to overcome until you are in the reception.
Compared to other Pousadas this one is not worth it's price. Book a room in the city and have dinner in the restaurant to get the view and you're better off.

The view is really great, and you are really located into the old castle. Be careful, some rooms have no view and are very dark... Ask for a room with a view. Not because of the view itself (the windows are pretty small actually) but because these rooms are really bigger and get more light. The view is fantastic... from the restaurant and from the bar. The price is extremely reasonable, so don't hesitate to make a stop at Setubal. This is not the most touristic place to be, but you will not regret it nevertheless. We enjoyed this hotel very much.

We spent a night at the Pousada on our way from Lisbon airport to the Algarve. The Pousada was very easy to find, thanks to the numerous waysigns. Unlike what you may believe from the official photos, the Hotel does not overlook the open sea, but rather the city of Setubal, including the port and noisy construction sites. Setubal itself is on the Sado river estuary.

The Pousada is really located on top of the castle, a long way uphill over stairs from the car park, so it is helpful to organize your luggage so you do not have to haul all your bags for one night. The staff was very friendly and prepared for our late arrival. The room was quite large. The breakfast was very adequate. Overall, it was a good experience for our first night in Portugal.

The market of Setubal is definitely worth a visit, if you can find it (tip: it is a large hall near the port with lots of cars parked around it.

We stayed three nights at this Pousada. The staff is very friendly, especially the clerk at the reception and Luis the Maitre D in the restaurant. The food was great. This is an ancient castle so it is expected that the rooms aren't standard hotel rooms. Our room was on two floors. The only trouble was getting the loggage to the second floor. The view from the restauraunt and terrace is spectacular. I found that the castle itself could be better maintained. The reception is very hard to get to from the parking lot. Many stairs to go up and no was to roll a suitcase.
I found that we overpaid for the room. We booked through the central booking agent of the Pousadas and I later found that I could have gotten the room for quite a bit cheaper through various websites. Shop around before booking, especeially at certain times of the year. However, there are only 15 rooms.
