I booked about two weeks before my stay, during a period (UNFCCC COP 25 conference) when there was huge demand for accommodations, so the price of this place and every other place were super high .The host seems to manage multiple properties and was taking care of many guests at the same time. Arranging check in was a bit difficult.
Thankfully the host is very communicative and professional. I could send them a whatsapp and they replied quickly. They explained everything in advance. The apartment is small but everything is new and working, it is exceptionally clean, in a good location and in a good neighborhood. It's perfect for 2 guests.
I would recommend it if, unlike me, you can book much more in advance or avoid such periods with high prices. The price I paid (nearly 200 US / night including all the charges) seemed abnormally high to me.
