Novotel Bosporus is absolutely a nice stay, but definitely not a 5-star- neither compared to other 5-star hotels in Istanbul or elsewhere, but rather a clear 4-star.
That impression strikes you already at arrival, at the unwelcoming, gloomy reception area that can be entered without the strict security controls and x-ray machines that are common in big Istanbul hotels, here with dreary, tiny desks with flatscreens on the wall listing the nightly prices.
A welcoming receptionist gave us a room on the 1st floor, where a stainy corridor with a strong chemical smell was under refurbishment, even though we asked for a high floor, claiming there were no other free rooms at the hotel. The room and bathroom are spacious enough, clean and comfortable, even though the interiors and materials underscore the general low-budget, lower end look.
The best part of this hotel is the homey rooftop restaurant where breakfast is served, with stunning views of and proximity to Istanbul's iconic skyline, great selection of food and good service. The price of 22 euro per person for breakfast however, is way over the top - but still worth it. Overall, we had a nice stay and enjoyed the proximity to Galataport and bustling Karaköy. But we will try another hotel the next time.
