We stayed for 3 nights in the appartment. It is located very nicely - the old town, castle and palaces are all in walking distance (keep in mind: sintra has hills). The appartment is cosy, and indeed not made for very tall people (we are both 1.80 and my boyfriend hit his head a couple of times). There are a couple tiny supermarkets around, and the kitchen is decent enough to make some meals - though it wasn't equipped extensively. The electricity also went off when we were boiling water and cooking (whilst having the lights on) - so it can't handle much. The appartment is quite humid and relatively cold. We actually quite enjoyed that, since it was hot out and it was pleasant that the appartment was cool. You can do laundry in the appartment & there is a tv with a lot of channels. Mariana also left some coffee, which was nice.
