The apartment was very well located close to the acropolis museum and lots of good restaurants such as Mani Mani. The AC worked very well and the washer dryer was extremely convenient.
Additionally, UpStreet's service was amazing. We had an issue with a power outage in the apartment. Immediately they told me not to worry about it and that they would handle it within an hour. So we went out to dinner and by the time we got back not only had the power been restored, but they moved us to an apartment a block away as a precaution while they could do a more thorough repair.
I can't imagine how harrowing this could have been with any other host but upstreet just took care of it and made it completely stress-free.
My only quibble is that the apartment could use double-paned windows to reduce the noise coming from the street.
