Our stay in Lisbon was great and Estela contributed to it.
The place was great; clean, cute and located in a quiet neighborhood, although close to Bairo Alto district, where the magic happens :) Metro station and the shopping market are also very close on foot.
Estela was waiting for us at the place when we arrived, along with a bottle of Oporto. They had prepared documents with suggestions for restaurants, bars, clubs and other places (e.g. Castle of São Jorge) worth visiting.
If you are looking for a stay in Lisbon, I highly recommend Estela's place!
