Considering how crowded Machu Picchu Pueblo is, this hotel’s location is great. It may be right next to the train tracks, but at least it’s flat and there isn’t constant foot traffic. Anywhere in this town will be noisy - either from the trains or the river.
Pros- staff will meet you at the train station to escort you to the hotel.(A very wonderful surprise). Friendly staff. Good breakfast selection. If you don’t see something, just ask. Good sized rooms.
Cons- needs updating. The bathtub/shower is a bit scary to use since you need to use a step stool to climb into the tall tub. It also has a significant downward slope for drainage. Older folks will need to be extra cautious getting in and out. The Ecco setting is nice unless u want the mini frig to stay cold. The power turns off when the room key is removed from the slot.
I was a little surprised they didn’t offer help with luggage when we checked out. We would have asked if we really needed help but we should have been asked considering this is a “nicer” hotel.
⭐⭐⭐⭐⭐ Great Location, Smooth Check-in, and Excellent Service
We had a very enjoyable stay at Casa Del Sol Machu Picchu. The location is excellent — just a short walk from the train station and close to the local market, making arrival and exploring Aguas Calientes extremely convenient. 
The check-in process was smooth and welcoming. The front desk staff were friendly, professional, and efficient, helping us settle in quickly after our train journey. The room was comfortable, clean, and provided a relaxing environment after a long day visiting Machu Picchu.
During our stay, the jacuzzi in our room was unfortunately not functioning. However, the hotel handled the situation very professionally and showed great commitment to guest satisfaction. They kindly offered complimentary drinks at dinner and provided a 20% discount on our meal to accommodate the inconvenience, which we truly appreciated.
The on-site restaurant and terrace were also very nice, offering a pleasant atmosphere to unwind in the evening.
Overall, a very positive experience with excellent customer service, comfortable accommodations, and a very convenient location. We would happily stay here again and recommend it to others visiting Machu Picchu.
