We loved it! The appartment is just next to the cute neighbourhood Alfama but still perfectly accessible by metro. You can see the river from the windows which is a great extra ;) We didn't meet Diogo and Filipa, but their friends were very friendly and accomodating. The equipment is great, too (it had everything we needed). The appartment is really spacious and beautifully furnished. I think the price-performance-ratio was super good and I would totally book it again :)
