Fantastic place and exceeded expectations. It has amazing views from the windows. It is very clean, modern, light and airy and has a perfect little kitchen. The extra touches such as a bottle of wine and a few things in the fridge were very welcome after the walk with luggage from the Metro - it is about 12 minutes walk but very pleasant past the shops and restaurants.
Check-in was easy as Manuela was in touch regularly about our expected arrival time.
The surrounding areas have lots to do, see, eat and drink! Manuela's husband tipped us off about a local place for lunch (Sinal Verde) at the corner of the street on our first day which was perfect for us after a long journey.
The apartment is also very quiet so we slept very well. You should be aware that there are four flights of stairs to the apartment so you do need to be mobile.
We will definitely be back next time we are in Lisbon!
