Positive experience: the house is recently renewed with high quality choices (heating, bathrooms, accessories); all furniture and appliances are brand new. We found it very clean and tidy on our arrival.
A sauna is present in the corridor (we did not use it).
The apartment is on the 1st floor. It is very well located: 3min walk from Wenceslas Square. Many small supermarkets in the street , along with some options for a meal very close to the house.
In any case the Old Town is not so far: less than 10 min walk.
The street itself during the night is definitely calm and quiet, no problems of noise during night time. Many parking possibilities if you come by car.
Some room for improvements... we are a family with children and one of them is a toddler, the agency provided us with a child cot (on demand) but without blankets – you should bring the child blankets. High chair is not available – even upon request before arrival.
Kitchen is equipped with most of necessary cookware and appliances but it misses cloth table and napkins (needed for more than a couple of days staying).
Note: the only 2 windows of the house are in the two bedrooms; curtains are more aesthetic than functional: they are not blocking the sun/day-light in the morning… this could be somehow annoying for some guests.
No air conditioning present in the apt (historical building), it might be pretty warm during Summers.
Overall recommended and consider my notes in case you have small children.
