In this post I will give you some information and suggestions for hotels in Thessaloniki. You have two choices for the locations of the hotel. Either at the city centre or at Panorama (which is where the wedding will take place and it's just 20-30 min drive from the centre). If you stay at the centre you have easy access to the bars, restaurants, shops etc (everything in walking distance) but you need to book a taxi to come to the wedding (it costs around 10-15 euros). Panorama, which is the "posh" suburb of Thessaloniki, has few shops, restaurants and bars ( most people go to the centre if they want to go out), but it will be more convinient for the wedding. Of course all the historical monuments and museums are in the centre of the city(there will be a post very soon about them).
If you want to book a hotel in Panorama I would suggest two hotels: Hotel Nepheli (http://www.nepheli.gr/default.aspx) or hotel Panorama ( http://www.hotelpanorama.gr/eng/ ). Both of them have a good reputation but I think the first is cheaper. Another hotel that is propably very cheap, but don't know how good it is, is hotel Pefka. They don't have a website but they are located in the centre of Panorama. This is a 2 star hotel, whereas the other two are 3-4 stars. I would suggest the first one.
In the the city of Thessaloniki you have more choices. If you want to spend lots of money I have 2 suggestion: Electra Palace ( http://www.electrahotels.gr/electra-thessaloniki// ) or Makedonia Palace ( http://www.lux-hotels.com/makedoniapalace ). Both of them have great views with the first being in the heart of the city (Aristotle square) and facing the sea. Both of them are quite expensive (~200E/night). For more realistic suggestion hotel Luxembourg is a good choice ( http://www.hotelluxembourg.gr/). It is located in the city centre, seconds away from all the good stuff (shoping, bars, restaurants, seafront) and in a reasonable price. Friends have told me that it's a good choice. More choices in the city centre are Zaliki Hotel ( http://zalikihotel.gr/hotel.html ) , abc hotel ( http://www.hotelabc.gr/ ), Plaza art hotel ( http://www.hotelplaza.gr/main_uk.htm), Park hotel ( www.parkhotel.com.gr/index_en.html ), Tourist hotel (http://www.touristhotel.gr/maineng.htm ). These are only some that I can remember. From a quick web search I found the following link which provides information and cheaper booking offers for hotels in thessaloniki:
You can have a look at the hotels and check which one you like. However before you pick one just send me (or Phyllis) an email so I can check the location of the hotel. There are no really dangerous areas in Thessaloniki, however some hotels are in really boring areas and a bit far from the main attractions of the city.
I will try to find some more information about hotels and will post more information soon.
That's all for now!
