Summer time rental would be not recommended as you can't open the window at all because: 1) smokers from ground floor comes in to the flat. can't open window. I guess this won't be too much of an issue during winter, but during summer, the flat gets quite stuffy and hot without the windows open. 2) big issues is you can't open the shade/curtain at all without being looked at by office workers directly across the balcony. felt like a fish in a fishbowl.
