We had a very pleasant stay at Grandpa's Inn, the rooms were basic but beautifully clean and comfortable. There was even a nice outdoor shower, which was really refreshing after a day of sunbathing! There wasn't any wifi in the rooms, but good wifi speeds could be picked up by the bar area. The staff were really friendly, they helped us with arranging taxis and planning the rest of our stay in India.
Grandpa's Inn is situated in a relatively quiet area of Goa, so we found we needed to take taxis if we want to visit the shops/markets. The Inn has a pool and sunbathing area so you can spend the day in the hotel itself.
