I really enjoyed my stay at the apartment hotel, but...
Couples be warned: Booked the apartment for two, but ended up going alone. There were two sets of towels, but only one bed sheet/duvet, and the bed was quite small for two people. I would not have wanted to share that place with anyone. Also the bathroom is one of those frosty glass, half see-through ones, which would make me really uncomfortable sharing the place with someone.
I had to check in on what I did not know was a public holiday, and I had not received any information on how to go about (i.e. no reference number had been sent to me). I used my European phone and called the company responsible for the apartments, and they guided me through the digital check in. If you had just landed with no EU-SIM card, you'd have to use roaming for that.
Would I go back to this place? Yes, it's clean and nice, and has a clear apartment hotel style of living, but if I return I will definitely only do it by myself again.
