We stayed for three nights and really loved it. The rooms are plain and unexciting but clean - and ours had twin beds - if that matters to you. But the hotel is utterly charming with a really strong 19th Century vibe. The elevator looks like it has walked straight out of an Agatha Christie Novel - with an attendant to match. It also has a great lobby/dining room with WiFi and a wonderful bar - where you can comfortably hang out read a book.
The hotel staff were also super friendly and organised any trips we wanted easily, cheaply and with little fuss. The day we had visiting the sites was great fun and very good value for money and the guide - Mina - was very friendly and informative without being obtrusive.
