Thuy is a very nice person even if we did not meet her in person due to her vacation but we were regularly in contact via whatsapp or phone.
The appartment was really very clean and everything you need was available as written in the description and worked. Good bed, kitchen and bathroom even washing machine and dryer.
The appartment is a bit darker than expected and you always need to turn the light on, but for us this was not important since we were anyway the most time of the day outside.
The parking slots are really difficult to find after 5 pm (as Thuy honestly described) and so we recommend to use BART or the Muni buses to go downtown, or if you need a car take a small one :-)
Overall we were very satisfied and recommend the appartment and we would rent it again.
