Stayed 1 week in late May - early June 2018.
In fact season is not started at that time: only Planpraz cable car and Montenvers train were open. Quiet time for tranquil hiking without crowds :)
Overall hotel impression: inexpensive basic accommodation in good location with very limited service.
Pros:
1. Very good location - centre of Chamonix, next to bus station
2. Quiet spacious apartment with balcony and beautiful Mont Blanc view
3. Fully equipped kitchen: microwave, electric stove, kettle, fridge, dishwasher, plates, cups, cutlery.
4. Possibility to order fresh bread for the next morning (but need to collect it from reception)
Cons:
1. Non-smoking room smelled like heavy-smoking one
2. Old linen and pillows were not comfortable to use
3. No room service during whole stay of 7 days
4. No refill for toilet paper, soap, etc.
5. Strong smell of the mould from kitchen sink
6. Inconvenient bath screen construction - water on the floor after every use
7. Slow WiFi internet connection - 2 MBit. Faster internet service can be purchased separately.
Things to do:
1. Visit tourist office to get relevant useful info
2. Use free buses and trains to quickly get anywhere from Servoz to Valorcine
3. Plan hiking routes in advance, keep in mind cable cars open hours and prices
4. Enjoy beautiful mountain views and nature!
