The appartment is OK and compared to other prices, relatively affordable. It's great that you have interesting books to read, kitchen appliances to use and some generic things present (like coffee, although I'm not sure if it's always present). The badroom is functional, but it does have some black mold and could use a bit of renovation. There is plenty of hot water for 2 persons (in case you wonder with the electric boiler). The shower was clogged, but water went away eventually and it has no risk of running over (simply your feet will be in some water). We stayed 9 nights and with 1 set of bed linnen and 2-3 sets of towels per person, found that something that can be improved. There is a washing machine, so you can wash your towels yourself if you like. It's a rather dark appartment and the curtains can't be opened, so to spend days there I wouldn't recommend. The location is really good if you travel by public transport as it's a 5 min walk from the train station Monte Estoril. You're close to the beaches.
We found that the appartment is according to the photo's and description. We chose it because of the upper floor. Beware that this comes with going up and down the stairs a few times.
