This hotel has all the luxuries one would expect from a chain like Mercure. The building is huge, at times feeling like a set for the film ‘Shining’. It is not for me, simply because it has no soul, no character or style. The fittings are cheap, the vibe a bit large group holidays. Spa is accessible with a 30 euro fee.

Il prezzo della spa non é più compreso nel costo del pernottamento alberghiero e devono essere noleggiato accappatoio e ciabatte. Tale variazione rispetto al passato non era evidenziata al momento dell'acquisto. Rispetto ad un anno fa il libello della colazione è peggiorato quanto a qualità e scelta. Nel complesso il luogo é gradevole

Struttura molto bella ed elegante. Personale adeguato al numero di persone ma non alla vastità degli spazi. Organizzato bene anche lo spogliatoio per restare dopo il checkout. Scomodo l'asciugacapelli visto che doveva essere tenuto sempre premuto il tasto di accensione. Bagno enorme tutto rivestito in marmo. Camera silenziosa. Due materassi vicini ma con topper matrimoniale che non faceva sentire gradini. Penso che torneremo

Dårlig oplevelse

Vi blev virkelig skuffet. Kedeligt hotel helt uden stemning. Dårlig, sparsom morgenmad og synes ikke personale var så imødekommende. Termisk pool og den alm. pool burde ligge adskilt, så man ikke skal ligge og lugte til det termiske bad. Dårlig oplevelse og vi tjekkede ud før end planlagt. Iøvrigt virkede el-laderen til bil ikke!

Sämre än vad det sägs.

För mig var boendet *** stjärnigt. Personalen var slapp. Billaddningen fungerade inte och det var därför jag framförallt valde hotellet. Maten var ok. Vid ena sidan av utomhuspoolen luktade det avlopp, äckligt. Det saknas finish för detta hotellet.

Linda toscana

É uma excelente opção para visitar o Val D’Orcia hospedando-se em um hotel e não em uma hospedaria. Um plus são as termas com água sulfurosa vulcânica que é uma experiência interessante

Hotel con terme, piscine e centro spa

Hotel molto bello che ruota intorno al centro termale interno. Abbiamo apprezzato la flessibilità degli orari di ingresso alle piscine sia prima del check in che la possibilità di fermarsi senza supplemento oltre il check out (utilizzando gli spogliatoi). Eccellente la colazione, ampio il parcheggio, comodo il kit spa fornito. Camera da sogno.

Acque fredde

Tutto ottimo solo una pecca le piscine delle terme erano freddine, fortuna della vasca solfurea ... alle rimostranze dei clienti l’addetto rispondeva che la temperatura era giusta senza verificare
