This place was amazing. Plenty of space for our party of six, including my 80 y/o mother-in-law and our two kids. Very clean, very tech savvy (a little overboard!) and extremely convenient. Close to all the action and attractions. Beautiful view of the palace and Alfama area from the living room. Olivia greeted us with a bowl full of fruits, coffee pods and wine. She provided good instructions and also helped arrange a visit to Sintra. She was extremely responsive throughout our stay and even promptly sent in the washer detergent as it was out.
Although the place is on the 4th and 5th floor, there is an elevator. Also, one of my big worries was that it was right on a busy street and I was assured (rightly so) that the double paned doors / windows block out the noise. The flat gets a great amount of breeze but we ended up closing the doors to the balcony as there was a lot of street noise and turned on the AC. Grocery store is a block away and plenty of restaurants and cafes around the corner. Very highly recommended.
A couple of minor things I mentioned to Olivia that could be improved upon is the ease with which you could open the front door. As good as it is from security perspective (extremely heavy, with three of four locks - felt like a bank locker strong room!), it can be a hazard if there is fire and you need to exit the place quickly. You need to use the keys to both enter and exit turning it a few times. I don’t believe my mother in law, who is 80 years old or my 11 year old would have been able to open the door without our help. There should be a bolt inside that could easily open the door. Although there is a touch button to open it, it worked only about 25% of the time. Secondly, the sink in the half bathroom in the upstairs should be changed. As fancy as it looks, it is very impractical and gets dirty quite quickly. I understand that the owner plans to make changes to this bathroom which should address the issue.
