Very clean and very stylish; may be style refined too deep to grade when it inflicts comfort - but for short romantic stay it is interesting and not become a problem. Flat is perfectly clean and host very nice and available for help; Alfama district OK just not interesting enough for come back (next time I try Sintra may be or some other small town around Lisbon). Flat may be uncomfortable for tall people (hogher than 180cm) as it have a lot of curved ceiling and you need to watch your head sometomes. But for 4 days I never hit my head :)
Mattress is very good, washing machine presented. I would prefer usual electrical tea kettle instead of stylish stainless steel kettle for heated on the oven; but well, all kitchenware is stainless steel series professional quality - not cheap Ikea staff
