The flat is pretty much as described. If you suffer from leg problems or have a bad general condition the steps might be a bit of a problem. They are steep and narrow. A big part of the flat (mainly above the bed) is less than 1,8m high, but this isn't a major issue unless you make it into one =)
THe balcony is small and is perhaps only good for smoking or the occasional wine glass and ofcoure ventilating the apartment. Two people can fairly comfortably stand on the balcony and enjoy the views, which are fairly ok. ONe can see the suspension bridge from the balcony.
Communication was good and efficient.
The flat is very nicely located at a trendy neighbourhood (probably contributing to the rising rents for the locals in the area...) with a lot of bars around the corner. There is a metro station entrance maybe 150m from the flat so if you are travelling from the airport you can reach the flat with one line change in less than an hours (one way ticket costs about 1,50). Taxi took us (when arriving) about 30 min and cost 20€.
If you stay here and enjoy hamburgers be sure to try out the insanely good hamburgerplace (Cultura do Hamburguer) a few blocks away. The popular tram line 28 also passes the building block in which this apartment is located.
