Very good experience.
Pedro and his team (we dealt with António and Luis) are very good hosts. They were friendly, helpful, on time for the check-in and available when needed (we had a sewage odour problem and António came within an hour to correct the situation). They give some chocolates and a bottle of wine to welcome you!
The loft is very clean and nice. the bathroom is also very clean with a big shower. It has TV with some US and british channels and we could watch some of the Rio Olympics at night. Internet connection is very good (at least 25 Mbps).
But the biggest advantage is the amazing location of the loft, right in the center of Lisbon! You can walk the whole city from it (except for the Belém bairro). There is a Mini Market just downstair where you find almost everything. There are a lot of restaurants and shops around. There is a lot of animation days and nights which is fun and as the loft is on the third floor with air conditioning, it is not noisy when the windows are closed. The subway is only 300 meters away and there is a tramway stop downstair.
The only problem (just to find one) is the ceiling height which is a bit low in some parts of the apartment for 6ft+ people like me.
we spent 2 stays there and we enjoyed it both times.
