My wife and I stayed at Tanamas House for one night only as we had to catch a flight early the following morning.
As we were coming from Ao Nang beach by bus and were dropped off at the airport, I called the hotel and in 5 minutes someone came to pick us up as promised.
The hotel is just off the main road coming from Phuket airport and consists of 5 bungalos. The room was spotless and well decorated, with all modern amenities such as brand new air conditioner, cable TV, coffe maker, kettle, frigobar, etc.
The hotel staff was always very helpful and took us to the beach with their tuktuk/minibus for 30 baht. As we couldn't find a tuk tuk at the beach to return to the hotel, we called the hotel and in 5 minutes again they arrived to pick us up. Nai Yang beach is not the best beach in Thailand but as mentioned by other travellers, it is very quiet and relaxing.
You can walk to the beach from the hotel but it will be a good 15 minutes walk.
In general, we were very positively impressed with the quality of service and accomodation at Tanamas House and would definitely recommend it to travellers that need to stay near Phuket airport or even if you are enjoying a few days in Nai Yang beach.
