We had high hopes for this apartment from the pictures, and we weren't disappointed. Communications were swift and directions were very accurate. We got the bus from the airport and it was 5 mns walk from Praca do Comercio, which made it a great location.
Alex met us at the apartment and gave us a good overview of the area. It was impressively clean, with some toiletries aswell as coffee, tea, wine, salt and pepper - the things you need but can't be bothered to buy, if you're only staying for a few days.
The beds were firm and comfortable, it was quiet during the night, although we did hear the Metro (I think) rumbling under the building in the morning, not early though.
There were plenty of guides and magazines left to look through. We didn't use the TV. Wifi was fast and reliable.
Hot water is from a combi boiler so we had to coordinate showers.
All in all, we thoroughly enjoyed our stay in Lisbon and this apartment is very much recommended.
