The host is nice and the apartment is pretty big and cosy. You would definitely spend a nice time there, and it is quite close to the subway and the starting station of the 28th tram (which is a big tourist magnet).
But there were two things that I am even ashamed to mention - hosts saved few euros on necessities. There is literally not enough toilet paper (4 guests for 3 nights, 1 roll), and when asked the host says "oh, we only supply it for one day, you need to buy the rest". So instead of enjoying Lisbon, I need to roam around trying to find the damn paper? That is just ridiculous, so 4 stars instead of 5.
Oh, there is a washing machine, but you need to buy your own detergent.
Apart from that - great stay, no problems. But I can't leave a 5 star rating for a host that decided to save less than 1% of the rent cost on stuff like toilet paper and washing detergent. I came to relax, not to run around and buy basic stuff.
Hope that would be fixed for the next guests. P.S.: all other places I stayed in Portugal had both paper and detergent, so it is not a typical thing.
