Lovely hotel with friendly staff. It was clean, modern, in good repair, with good amenities and a comfy, small-ish room. I had a message within 10 minutes of booking offering extra services. An extra pillow and iron were waiting in our room for no extra charge. Staff gave recommendations, answered questions, gave converter plugs for electronics upon request, etc. Petros is around the corner from Taksim, a 15 minute walk in either direction to the Metro, and taxis and buses meet just across a main busy road. Sound-proofing is decent in the room, but there’s so many restaurants, bars and cars outside that it gets very noisy; ear plugs on weekends are essential! The week was quieter though. Just keep the window closed and put the aircon on a timer before bed. Would 100% recommend Petros to others and would stay again.
