We very much enjoyed our stay in this tiny and very modern apartment. It's location is amazing and couldn't be better to explore the old district of Alfama.
The equipment could be a bit better (e.g. more towels), but you will definitely find everything you need. Also Ana, who checked us in, was very kind and helpful with everything!
Be aware that the door is narrow and the stairs are quite steep. But there are a lot of stairs in Alfama anyways - perfect for the fitness ;)
