I stayed 2 nights in Jun, loved it!! Superb location, superb host, superb stay experiance & the place look just like the pictures and super clean, it's bright and airy.
It's newly renovated at quite street yet super closed to Belém side of attractions, i.e 3-10minutes walk away from Jeronimos Monastery, Belém Tower and even closer to the famous Pasteis de Belém.
Ask them for bus that goes to central for the rest of attractions it's easy - tram is always full, so bus is easier to get you around.
Fully equip with kitchenett and washing machines.
Ines was swift in responce and queries, Fernando met me on arrival, he gave me full house orientation and diligently show me all area of interests, and restaurants etc.
I am so glad he point me direction for various train stations for my next destinations.
Ensure you do not miss the Palace da Ajunda - it's superbly preserved and not much tourists.

Book Ines and Fernando's you won't go wrong :)
