We booked this hotel for a really good price and it turns out to be probably the best value hotel we have ever stayed in. The hotel is easy to find, situated a few minutes walk through town (passing restaurants and shops) from Santa Domenica train station. On arrival we were immediately given a room upgrade. The room was nice, with access to a very large balcony with sea views shared with the rooms either side. Breakfasts were included and these were good, and we liked the hotel and the staff so much we ate our evening meals there three nights - delicious food and good value for money.
The hotel is about a 20 minute walk from the Riaci beach (part of it down quite a steep hill) and a 30-40 minute walk to nearby Tropea, a lovely old town with its own beach. It is also worth taking the train to Ricadi and walking to Capo Vaticano and the Grotticelle beach, plus take a trip to Pizzo as that is very nice. Note that Santa Domenica station doesn't have a ticket office or machine and they charge 5 Euros extra on board - we were let off that and had to jump off the train at another station to buy tickets. After that I downloaded the Trenitalia app to buy tickets in advance.
In summary, we recommend the Hotel Umberto and would like to thank the staff there for being so welcoming.
