I booked my flight to London with a long stop in Istanbul so I could go out and look around.

Turkish Airlines was still 7.4 million đồng whether I looked three months or one month ahead. Close to departure it had jumped to 15 million :D

Unfortunately I hadn’t looked at the journey home. Flights to Hanoi from Edinburgh, London and Manchester were 20–30 million đồng, and the trains were expensive over the holidays too. I’d already booked the outbound flight, and everything was nearly three times the usual price.

Visa online, pay the money that I have, and I almost got scammed because of so many scam links. At first I filled in a link, n say full slot normal, choose the service to do fast is higher price but still have to wait a few days. Something seemed off, then I found https://evisa.gov.tr/en/apply/. I filled in a few details, paid $51 and got the visa. The visa pdf was sent to my email and I was looking for it until the day of my departure :D

The night before I checked in to choose a free seat, the stretch from Hanoi - Istanbul long flight so choose a seat near the gate, the stretche from Istanbul to London 4 hours then sit near the window, however, still no boarding pass because you need to check luggage at the counter, after the procedures boarding pass can be downloaded on the phone, at that time I did not know so ask the staff to print paper card for.

This time I wasn't asked for a return ticket, customs didn't ask anything.

The flight time is about 10-11 hours, as long as you fly long trips also get used to.

Free wifi on board but it takes about two hours to use it. I have QR scan to buy 100 MB for 8 USD that still text and send / receive photos so do not buy.

Wifi on the plane is enough to watch my story like this.

I’d taken €40 to an exchange counter earlier. It was my first time changing money at a counter. I usually went to Hà Trung in Hanoi, but this time I’d found a gold shop nearby that exchanged pounds, so I hadn’t gone there. 40 Euros = 1415 Turkish Lira, I didn't think much at the time, I just got what I wanted, and then I calculated and I found that the exchange fee was 10 Euros.

Tram in Istanbul I subjectively did not know before, troubled to buy Istanbul card for 165 TL. I gave the 200 TL bill and didn't see it back so I looked at the invoice and found the Top-up value was 35 TL.

I have downloaded two apps to book train tickets before not because I can not find the destination as on Google maps so I have to risk putting my card on the train and go with Google maps.

Walk back to bed for a while, charge my phone, and then go out and go for dinner.

It was cold, hungry, and I just walked out of the hostel and saw a pack of cats, about five of them, lying out on the street.

This one goes around and climbs on my shoulder and sleeps. I'll let him lie there for a few minutes too, because I can't stand the cold.

I was staying in the centre, a short walk from a market. I went round looking for something to eat but found mostly restaurants with dishes around 200,000 đồng. The old menus on Google Maps showed about a third of that price. I don't know when the whole city of Istanbul has been tripling the price of everything.

Because I was so hungry and couldn't find rice, noodles, and soup, I ate corn for a while, which was also good, but there were places that were too salty so salty. 40 TL = 25k VND, it's cheap but I didn't change the price to Vietnam so I thought it was expensive:D

I'm walking around and I see a hotdog stand that reminds me of two good 3 Euro hotdogs at RomaTermini and German sausages.

140 TL = 85k, a little expensive and not good.

Finally found a place to buy cheap Doner Kebab although I was full but I still wanted to try.

I chose a small size 80 g but also lucky n big, eat a lot because the price is not cheap. 225 TL = 136k VND

I didn't eat enough, so I put it in my bag and took it home. Along the way, I gave the cat a piece of chicken, which it didn't seem to like, and I made enough for breakfast the next day.
