How we score

Each score is worked out by code from the facts this page shows, never from guests’ ratings or a writer’s opinion, and is given as 1 to 5 dots.

Near the sights: how close the nearest listed sight is, and how many are within 1 km. Rooms: the room sizes we show and how many types there are. Facilities: how many kinds the hotel lists (dining, pool or spa, fitness, front desk services, comfort and access). Wellness: spa, hammam, sauna, steam room, pools, gym and massage.

A score is left out when the hotel’s facts are too few to judge it.

Where the hotel sits, and how far things are

SuB Karaköy - Special Class is an independent hotel on Necatibey Cad. 91 in Istanbul.

Both of Istanbul's airports are some way out: Istanbul Sabiha Gökçen International Airport (SAW) is about 31.1 km away and Istanbul Airport (IST) about 32.8 km away, in a straight line.

Galata Tower: about 0.4 km
Sirkeci railway station: about 1.2 km
Taksim Square: about 1.4 km
Topkapı Palace: about 1.5 km
Süleymaniye Mosque: about 1.7 km
Hagia Sophia: about 1.9 km
Sultan Ahmed Mosque: about 2.3 km

Two 20 m² rooms: a queen double or a twin for three

The hotel has just two room types, and they are the same size: the Design Double Room and the Design Twin Room are each 20 m², and both have a city view. The choice between them comes down entirely to the beds.

The Design Double Room has one queen bed, which suits a couple or a solo traveller who wants a double bed. The Design Twin Room has two twin beds and sleeps up to 3, making it the only room type with a stated capacity above two; three adults travelling together, or two who prefer separate beds, would take this one. There is no larger room in the hotel, so a group bigger than three would need more than one room.

With only two room types and both at 20 m², nobody choosing this hotel is trading up or down between sizes; the decision is simply queen bed versus twin beds.

Rules: check-in from 14:00, no children, fitness facilities

Check-in is from 14:00 and check-out is until 12:00. Children are not allowed, so the hotel is an adults-only property in the strict sense: it is not a question of children staying free or at a supplement, they are simply not permitted.

The hotel has fitness facilities of its own, so a morning workout does not depend on anything outside the building.

Who the hotel suits, and who it does not

In short, this is a small, independent, adults-only hotel with two same-sized city-view room types, a pet-friendly policy and fitness facilities. Anyone whose priorities are a large room, a choice of suites or space for a family will not find them here.

Couples: the Design Double Room with its queen bed is the natural fit, and both room types have a city view.
Groups of up to three adults: the Design Twin Room sleeps up to 3 and is the only room type that does.
Travellers with pets: pets are allowed, and children are not, so the guest list is adults and animals only.
Anyone who wants to keep up training while away: the hotel has fitness facilities.

No pool, two 20 m² room types, about 0.4 km from Galata Tower

The hotel's facilities do not include a pool, so if a swim matters to you, this is not the property for it. The room offer is fixed at two 20 m² types, so there is no upgrade path within the hotel: what you see in the two room types is the whole range. Against that, the hotel is about 0.4 km from Galata Tower in a straight line, with Taksim Square about 1.4 km and the Sultan Ahmed Mosque about 2.3 km away, and it accepts pets while excluding children.
