Sorriso Hotel Due: adults-only hotel with hammam in Laleli

Sorriso Hotel Due stands in the Laleli district of Istanbul's Fatih area, an independent hotel rather than part of a chain. Laleli Mosque is about 0.2 km away in a straight line, and Süleymaniye Mosque about 0.8 km. Fatih Istanbul Mosque is about 1 km, and Sirkeci railway station about 1.8 km.

Further out, Sultan Ahmed Mosque is about 1.9 km, Hagia Sophia about 2.1 km and Topkapı Palace about 2.4 km, all in a straight line. Of the two airports, Istanbul Sabiha Gökçen International Airport is about 32.2 km away and Istanbul Airport about 33 km.

The five room types span a wide range of sizes, from the Economy Double Room at 15 m² to the Connected Room at 40 m². The Economy Double Room is the smallest and best kept to a couple travelling light; the Standard Double or Twin Room, at 20 m² with one double bed and space for up to 3, gives a couple more room or a third guest a place to sleep.

For groups, the Standard Triple Room has three twin beds in 25 m² and sleeps up to 4. The two largest rooms suit parties who want to spread out: the Family Room at 38 m² and the Connected Room at 40 m², the latter with a city view. Note that despite the Family Room's name, the hotel does not admit children, so these larger rooms work for groups of adults rather than families travelling with kids.

The hotel's wellness offering centres on a Turkish bath and hammam and a steam room.

The property is wheelchair accessible, which travellers with mobility needs will want to weigh alongside the room sizes when choosing.

Check-in is from 14:00 and check-out until 12:00, a schedule that suits both morning arrivals and a relaxed last morning. Two rules are firm and worth knowing before you commit: children are not allowed, and pets are not allowed. The hotel is entirely adults-only in practice, whatever the room names suggest.

Groups of three or four adults are well served by the Standard Triple Room and the two largest rooms, and the Connected Room adds a city view.

It does not suit families: children cannot stay, so anyone travelling with children should look elsewhere. Nor does it suit travellers expecting resort facilities such as a pool, or those bringing a pet. Solo travellers and couples on a tighter budget may find the 15 m² Economy Double Room cramped, in which case the 20 m² Standard Double or Twin Room is the better pick.
