Location of the hotel and its spa are the only positives this hotel has. There are many negatives.
Pros: The main positive about BC Spa Hotel is the location. It is located right next to the river which runs through Dalyan. Due to this location, the mountains on the other side of the river can be viewed from the hotel, such as from the pool and from the room. The hotel being situated next to the river makes it really special, as you can sit and eat breakfast/lunch with a view of the river and mountains, which is very pretty. The location of the hotel in terms of distance to the town is also great, as you can walk everywhere in 10 minutes, like restaurants, shops, and the boats that you catch to travel along the river. The hotel is also very quiet as there are no loud restaurants/bars nearby. One aspect of the hotel that we were very happy with was the spa. We were gifted a hammam treatment and massage by a friend, and thoroughly enjoyed it. It was very relaxing, and the staff were excellent and so friendly. Due to it being a gift, I do not know the prices and how expensive it is, but I think it would be worth a treatment there if you are staying at the hotel.
Cons: There were many broken items in our room such as the air conditioning, the TV, the fan in the bathroom, the fridge, the clothes horse, the wardrobe doors, the shower. This meant we were constantly having to ask reception to fix things in our room, resulting in us not having a very smooth or relaxing stay. Additionally, there was supposedly a leak from our room to the room downstairs, so we had to move rooms in the middle of our holiday, which was far from ideal. We had unpacked everything at this point, so it was a big pain to have to move all our items and suitcases to another room. You would think that with this many problems we had, the staff would be apologetic and doing everything they can to help fix the errors, but the customer service from nearly every staff member was appalling. They had attitude, and didn't seem like they wanted to make our stay the best possible. We needed pool towels to sit by the pool and go for a swim, but when we asked for some at reception, we were told there were none available, and there would be some ready in 3 hours. Not only is this unacceptable, but they didn't offer us any shower towels that they give out for the rooms, which meant we had to ask a cleaner who was happy to give us 2 towels. It is as though the staff do not care about making their customers have the best experience possible. We ate breakfast on the first morning, but did not enjoy it at all. The room the food is kept in is extremely hot (hotter than outside!), and it is full of flies, which is very unhygienic. As Turkish people, we could tell that this food was not of a very high standard. Therefore, we did not eat the breakfast at the hotel again, but found lots of other places in the town that were excellent and very cheap, such as Kral Bahce Cafe, and also Altin Tava Cafe for amazing gozleme (Turkish pancakes). A friend who has been visiting Dalyan for decades says BCSpa has changed drastically in the last 2yrs; it was never like this before!
