From the first moment to the last, the reception and concierge were great. Firstly, I don't know if it was the front of house or the Hotels.com perk, but we got upgraded to a Suite from our Deluxe Room. Very spacious and slept so well in our king size bed. Very happy with the amenities in the room. Only downside to this review is some TV channels weren't working.
There were options for breakfast and we had a drink at the top of the hotel overlooking views of Bangkok.
Location wise: it's at the end of Soi 11, which is a 5 - 10 minute walk (depending on walking speed) from Nana BTS station. You'll pass all the Western bars and restaurants which get lively at night. Alternatively, it's a 15 minute walk to Asoke BTS / Sukhumvit MRT. Otherwise, if you want to avoid the heat/pollution, taxis and tuk tuks roam the street, but will probably overcharge you for a short trip.
Talking about transport, concierge are more than happy to assist you to go anywhere including our departure to the other side of Bangkok.
We will be back to end our holidays in Thailand at the Solitaire hotel. Hope it's as good as our first stay!
