Mos Repos is a 4* for sure, with the usual shower slippers, bathrobes, nice towels and toiletries. Buffet breakfast and dinner are very good and are a great way to try an array of traditional Greek dishes. Staff are attentive and friendly. Housekeeping hours can be rather sporadic.
The hotel is quite elegant, but very old. Hence, we found things a little less well maintained than we would expect in North America.
The hotel sits about 2.25 km from the old town. A nice walk along the promenade for able-bodied people but a bit inconvenient for others. Taxis to and from the airport or the ferry port are very expensive. Plan on paying €20 for even the briefest trip
