We had an enjoyable stay at Jean-Philippe and Xuong's place. They were both excellent hosts and nothing was too much trouble for them. There was a problem with the lift when we arrived which took a day and a half to fix. The apartment is on the 5th floor and 104 steps ( yes- we did count them) and was getting a bit much for a couple in their lates sixties but to the boy's credit the pushed the lift company to fix it.
The location was perfect for us- 5 minutes to the station, and about the same to the lake and the Old Town. There are numerous restaurants on the surrounding street and the neighbourhood seemed very safe.
We did not realise ( our fault) that it is a shared apartment but our hosts were not intrusive. I would definitely recommend this apartment (which has a lot of character)
