It's a nice and spacious apartment. We had a very comfortable stay there. There are two levels: on the first there is a kitchen and a living room; on the second there are two bedrooms and a bathroom. The kitchen is fully equipped; beds are very comfortable. Interior is modern and stylish. Wi-fi connection was, maybe, not the fastest one, but stable and completely enough for us to work with a photo storage and surfing the web. The only problem may be a busy street for light sleepers, but this can be solved by closing a window (there is an air conditioner) or using another bedroom with window facing backyard as it's quiet there. There is a supermarket nearby (Pingo doce) and some places to eat, so we had no problems with getting food. The metro is within five minutes walk; most places of interest can be easily reached by foot.
We would definitely choose this apartment if we stay in Lisbon once again.
