My girlfriend and I spent two wonderful, romantic weeks at this studio near the beach. Filipos was a friendly and helpful host. He gave us suggestions for what to do on the island and was available whenever we needed something extra. He also provided us replacement bedding and towels after our first week. The studio itself is cozy but had everything we needed. The place was clean and the bed was comfortable. We kept food in the fridge and cooked some meals in the kitchen using the stove burners without a problem. The patio was great for relaxing, reading, eating meals, and drying our clothes.
You are right under another home so sometimes we could hear a family with children talking or coming and going from the patio above, but visually it is separate and pretty private. The shower is very small without much hot water but it was okay for us. The wifi was inconsistent, but Filipos mentioned this at the start and also provided us a sim card we could put into our phones that had cellular data. This worked for us but meant having to switch out our sim cards frequently.
Easy parking, a lovely beach, and a hotel restaurant are all about 5 minutes walking down the hill from the studio. We ate at restaurants all over the island and thought the restaurant nearby had some of the best food we had during our whole trip! All in all, we had a great time in Tinos and loved our stay! We highly recommend and would happily stay here again.
