UNION HOTEL KARAKOY: adults-only, 0.4 km from Galata Tower

UNION HOTEL KARAKOY is an independent hotel on Tersane Cd. in Istanbul, postcode 34421. It stands about 0.4 km from Galata Tower, in a straight line. A cluster of well-known mosques and palaces sits between about 0.7 km and 2.1 km away, and Sirkeci railway station is about 1 km away.

Both of Istanbul's airports are a similar straight-line distance from the hotel: Istanbul Sabiha Gökçen International Airport (SAW) about 31.6 km away and Istanbul Airport (IST) about 32.6 km away. Each is more than 30 km away in a straight line.

• Galata Tower: about 0.4 km, in a straight line
• New Mosque: about 0.7 km
• Süleymaniye Mosque: about 1 km
• Sirkeci railway station: about 1 km
• Topkapı Palace: about 1.6 km
• Hagia Sophia: about 1.8 km
• Sultan Ahmed Mosque: about 2.1 km

The five room types fall into two doubles and a trio of annex junior suites. The Standard Double Room measures 21 m², has one double bed and sleeps up to 2. The Superior Double Room measures 22 m², also has one double bed and also sleeps up to 2, and it has a sea view. For two adults the difference between them is a single square metre and that view; the bed and the sleeping count are identical. Neither double is spacious: 21 m² and 22 m² are compact rooms for two people.

The three annex junior suites each measure 35 m². The Annex Junior Suite and the Annex Junior Suite - Sea View each have one queen bed and one sofa bed; the Sea View version has a sea view. The Annex Junior Suite - Partial View has one queen bed and one bunk bed and has a partial sea view.

Because children are not allowed, the bunk bed in the partial-view suite is a bed for adults: that room is the one for a group of friends travelling together. The two sofa-bed suites offer the same 35 m² with a queen bed and an extra bed, for adults who want more room than a double gives.

Check-in runs from 14:00 and check-out until 12:00. Children are not allowed, and pets are not allowed. Together these rules make the hotel an adults-only property in the strict sense: no room type, not even the suite with a bunk bed, is open to a child, and no pet stays either.

Parking is on the street. A health or beauty spa is nearby.

The hotel suits couples and pairs of adults, who choose between the two doubles on size and view, and groups of adults, who have the 35 m² annex junior suites. It is an independent hotel, not part of a chain.

It does not suit families with children or anyone travelling with a pet, since neither children nor pets are allowed. Travellers who want to keep a car at the hotel should also note that parking is on the street rather than in a garage of the hotel's own.
