I stopped at the Flipper hotel a few years ago-It was not 4//5 star . But it was clean /Situated conveniently to all the local sites . If you want to move a bit further along Jomtiem is a little less busy /Cheaper possibly ?
I had root canal work done at Mahidol University in Bangkok. It is a Dental school/Teaching university . It took a bit of time to be clerked /ID card made .The treatment was professional and painless . MY wife is Thai so there was no language barrier . The cost was very reasonable . Go for it -Dental pain is not fun in any time /place .Good Luck.
I have flown with Qatar airlines -I liked Doha airport /Flight staff . My only negative was the time keeping was not as good as Emirates . Tomorrow Boris is going to make an announcement about Covid restrictions .So stay tuned ?Have a smooth /enjoyable trip.
The first time I sent money to Thailand I was wrongly told that I needed an IBAN number . I went on the phone and found out the correct method . I guess they /Me learnt something .If I recall correctly you need an IBAN number for transfers within the EU ?
There was one in 2019 (when I last came back to Thailand with my wife). Of course Covid might have changed that . I know that they did a good job on my partners case.
