Very clean and modern unit. The building is located right in the heart of the tourist district of Lisbon. There were plenty of great restaurants only a few blocks away in all directions. The unit is large compared to other accommodations we've stayed at in Europe. We appreciated that it had a full kitchen, even though we never used it since we were out and about all day.
The only downside of being in such a popular location is the street and building noise, even very late into the evening. Nothing a set of earplugs couldn't solve for us though.
