For starters I would like to strongly recommend this place to every person discovering Lisbon.
Isabel is a wonderfully warm host with big penthouse apartment overlooking the river. The river-view means that there are three windows and a massive terrace with direct view to sun and moonrise, that are both absolutely magical.
For people hungry for wifi, there are probably better places, but for anyone who wants to enjoy their time in Lisbon and take a walk in the neighbourhood - there are plenty places to eat at on doorstep and supermarket just downstairs. We preferred walking to city centre (because it is all downhill) but uber will not be more than 3-4 euros to the buzzing centre.
After almost a week there, I'm sure next time in Portugal Isabel will have to hear from us once again!
