We had a great stay at Sandrine's house in Sosua / Puerto Plata area. Prior to our arrival we did read some mixed reviews, however our experience was great!!
Sandrine was extremely prompt when communicating with us prior to our arrival and any questions we had. Checking in was seamless and she provided us with all the information for the house and services that could be arranged. I would definitely recommend renting a car if you are visiting as the house is up in the hills and no services are in walking distance, however, you may not want to leave the house. The house is secure and the area has a security gate for entrance, we did not feel unsafe for a minute. The wi-fi and cable worked excellent for us as well.
The house was exactly as pictured and the views were actually better than advertised. The house is super contemporary, the A/C in the bedrooms worked extremely well (we had to turn them off during the night as it got too cold, ha), and all parts of the house were in good condition. The pool is great and perfect for lounging by for a full day. Being in the tropics, you would expect bugs, and there were very, very few in general even with having the doors open. We did have one scare with a large spider that ended up being more funny than off putting, but again that's what you would expect in any place that has humidity and warm weather.
Sandrine provided us with her WhatsApp contact and we had no problem at all communicating with her. She gave us great suggestions for places to eat and visit in the area as well as arranging a chef to come in and cook a typical Dominican diner at our house one evening. The house comes with a price listing for services as well as the costs for the mini-bar, so there was no guessing or surprises. The staff do conduct a thorough check-out making sure nothing is missing or broken, that you will be charged for. We accidently broke a glass one night that we did pay for, but again that info is provided in the house guide provided when you check-in.
All-in-all a very nice house, great pool and views of the ocean, and a quick drive to town and the beaches.
