Are there any bars and restaurants in walkable distance from the hotel?
No. The hotel is located outside Kardamena in a complex made up of 4 Mitsis hotels. Kardamena is a 10min taxi ride away. We were told there was a bar accessible along the beach but we never ventured that far.
There's one bar/disco just off site, fabulous place
I believe the closest ones we found were in Kardamena Nice walk but we used to get taxi back 5euros Enjoy
Only one walkable but taxi is 5 mins if that to kardemena
Oh my gosh, V489USpeterg is correct! Please ignore my answer...I thought you were referring to the resort in Crete which I visited in the previous year. Kardamena, which is a 10 minute taxi ride away, or very easily accessible by bus (departure and return times are available in the lobby and the bus stops right outside the hotel) is lovely during the day, but was not very pleasant once dusk hit.
There are several lovely little places--cafes, bars, shops, restaurants--along the strip that's just outside the hotel, as well as an excellent supermarket that's a slightly longer walk away (20-30 mins, I can't remember now). It's one of the things I missed most about the Mitsis I visited this year in Kos, which was situated in a complex with very little around.
