I visited Tinos for a wedding and stayed at Vaggelis' place for 5 nights with my partner and another couple. There was a lot that was great about the accommodations, but there were some drawbacks too. The space itself is wonderful, with very comfortable beds, a homey and comfortable atmosphere, and a fully appointed kitchen (we used it only for breakfast since the food on Tinos is so good, but I could easily imagine using it as home base for most meals). The terrace patio is especially spectacular, with amazing views of the sea and a particularly comfy hammock. Unfortunately, we were unable to truly appreciate the views because of the construction occurring from c. 7am to 3pm each day that we were there. The title of the listing mentions a pool but at the time of writing this review (early June 2022) the pool in question is still under construction, as are the two pools at the two adjoining villas. When we first arrived on Wednesday night we were told that there would be workers the next day from 7:30 to 2, which we were a little put out by but we were willing to ignore it for one day. When we woke up at 7:30 on Friday to the sound of the cement mixer we got in touch with Vaggelis who assured us that there would be no workers over the weekend. That was not the case, and after being out late to wedding festivities on both Friday and Saturday night we were all woken up again before 7:30 on both Saturday and Sunday, each time after assurances that there would be no disturbance the next morning. This was by far the most frustrating part of our trip-- and we all agree that we would have looked for accommodation elsewhere if we had known that this was going to be our experience.
There were some other kinks in the process, including no internet or water when we arrived. The water was not Vaggelis' fault, but the result of a municipal water shut-off, and we were provided with lots of bottled water so that we could at least flush the toilets and brush our teeth, but that was certainly a bummer after having spent more than 24 hours traveling internationally. Water was restored midmorning the next day, but it is something I would recommend travelers be aware of when visiting Tinos, since this seems to be an island-wide problem. The internet was less of a hassle, as we were able to piggy-back off of the wifi next door (with our host's permission) until a tech was sent out on Thursday night to fix the issue. The washing machine is also in the next door villa, which was a hassle and I can imagine when all three villas may be rented out in the future could become a problem. Checkout was also a little problematic-- I had texted Vaggelis the morning before we left to confirm that we were leaving the next morning and asking for instructions regarding the key. I did get a response that night about where to leave the key, but it wasn't until 1pm the next day (when we were already off the island) that I got a follow up text with instructions on shutting up the house.
We all agree that down the line this could absolutely be a five star property, but for us on this visit that was simply not the case.
