For the price, I can't really be that picky, so nothing really.
Very friendly and helpful staff. I found the location to be very good; close to the main square and a very short walk to the castle, but also very close to the park where a medieval fair was taking place that weekend. The price I paid was excellent and while accommodation was pretty basic, it was very clean and the room size was appropriate. I did not have breakfast included (it was 5 or 7 euros extra, which I found to be expensive), but there is a supermarket a couple of blocks from there where you can buy yogourt, pastries, etc. The room had a mini-bar, so I could keep drinks cool. Great option in Tomar. There is an elevator, so no need to go up and down the stairs with your backpack or luggage.
