We stayed at the lamp guesthouse for 3 nights. The location was very good, only a few minutes walk to the historical places such as Blue mosque, Hagia Sophia, Topkapi palace, yerebatan, …. The service was excellent, the room was absolutely clean and the bed very comfortable. The staff of the hotel was very helpful and very friendly: they organise city trips and also pick up from the airport. We certainly will recommend this place to our friends for their stay in Sulthanamet, Istanbul.
