This is a great, modern and well maintained apartment in the heart of Lisbon. The owner is very responsive and accommodating. However, we had to move out as soon as we could due to the terrible construction noise in the building next door. The sledge hammer noise started as early as 8:30am and continued intermittently till 6:30pm Monday - Saturday. We found it impossible to sleep, work or even be in the apartment during this time. The construction manager said that it will last for another couple of months.
