What for a great place to stay! Yes, you have to climb a hill to get there - but the view is outstanding. And just in case you've eaten too much, there are also trams and busses.
The contact in Lissabon is Joana and she is great. Really friendly and helpful with a lot of places to go. Thanks to her we had the real Lissabon experience in authentic restaurants throughout the city - even walking the hills didn't prevent us from gaining some weight ;)
We absolutely recommend this place and will be happy to come back one time. Obrigado!
