Excellent location (virtually across the street from acropolis museum), quite reasonably priced, clean, and with apparently complete kitchen (but didn't use). Has a balcony, which would be nice in warmer weather. Also metro stop was just down the end of the block.
Location is also on what is essentially a pedestrian street with restaurants (convenient in itself), which means there were essentially no late night traffic noises for a quite sleep.
Check-in meeting was prompt. Host seemed flexible and aiming to please, but had some communication difficulties as it was via email (below).
Issues:
--had trouble using the wireless connection. As instructed by the host, rebooted router and was finally able to connect, but then lost it after about 5 min. Had two devices (phone & tablet) which behaved differently---so not impossible some of the difficulty was on my end?
--Had some trouble figuring out how to control the heat, failing to get control of it the 2nd night.
--beds were VERY VERY hard. was tough on a 60 year-old back.
overall quite a nice stay, the hard beds being my only reservation in imagining a repeat stay.
