This property has a great location if you want to get a feel for Portugese culture and see many of the main historic sites in Lisbon. The 28 Tram runs nearby, and many sites are walkable from here, great Fado nearby.
However, there are a few key factors to note: 1)This is a 3rd floor walk up a very narrow spiral staircase, typical for an historic building, so be prepared. 2)the balcony pictured is not deep enough to sit outside, the stools pictured take up the entire space 3) the water view is often obscured by the huge cruise ships that come in and dock directly in front of the appartment view, so you will be looking at the side of a cruise ship - not the river. 4) the appartment is located in a no car zone, so you have quite a walk with luggage to reach it.
This space is ideal for a short stay maybe 1 week max. I was there for almost a month, the staff was most helpful getting my luggage up to the appartment upon my arrival, but refused to help when it was time to check out. Also, there was a big push to get me out to prepare for the next guests. I had some appointments early the morning of check out and the staff got very nasty when I declined their offer to store my luggage in their nearby storage unit. I was traveling with a small dog and they suggested that I store her there too! I did not ask for a late check out but, they were clear that getting in to clean for the next guests was their priority and I was in the way. An unfortunate end to my stay.
