The view from the apartment is fantastic and it is very nice to be able to sit on the balcony and watch the sun go down. Maybe we are a little weird since I read many of the reviews and they are all super-positive, but this were some of our observations for you to consider:
-The bathroom windows are clear glass with no blinds. Given that the apartment is overlooked at the back it was a bit disconcerting seeing someone in full view. There is also a beam across half of bathroom which given that I am tall (198cm) meant I had to be extra careful with night-time visits
- The shower is in the bedroom. The access is awkward again due to the sloping roof. Given my height, I had to stand under the skylight to be able to stand up straight. There is also a missing blind in the bedroom with a clear view in from the house overlooking the bed
- Given the apartment is on the top of a hill, its a big climb (150 steps+) before the three flights up to the apartment. It also generally took us more like 25 mins to walk into the main town area, or about 15 mins down the holl to the metro. It's good at keeping you fit, but it meant that it wasn't easy for us to pop back to the apartment after exploring to change and freshen up for the evening leading to long days.
I know that not many people may want to work while at the apartment, but if you do, bear in mind that the apartment doesn't have ac. It's on the top floor and it got quite hot during the day as we were having an unseasonable hot spell (we worked from the apartment in the week daytime). In addition, the desk chairs are garden chairs and not comfortable for any period of time. The upload speed of the WiFi meant Skype calls could be problematic (<1 mbps). During the day it was also quite noisy as they are building an apartment a few houses up which meant we could hear constant drilling which kind of got on our nerves.
In spite of these, we did have a wonderful time and I would highly recommend Lisbon as a destination.
