Great place and great host.
Belem was very kind and helpful.
The room and all of the flat equipment was amazing. Everything nice and clean. Fully equiped kitchen if you aim to cook.
Up to 5 minutes for metro and about 20-30 (afoot) for city very center. Cozy restaurant technicaly in the same building (not that fancy one few steps down the street) and little grocery just by (and few more groceries and supermarkets in close neighbourhood).
