We have stayed at Mansard apartment during the midsummer festival this year and if has been very enjoyable and comfortable stay.
The apartment is very spacious, even more than it is aparent from the pictures. Inta, the owner, has been very welcoming and adhered to all the nuances we had (baby cot, baby chair etc). The apartment is very clean and the decor is fresh and modern. It is close to the central Riga, yet feels very quiet and away from the city's noise.
We had two kids with us and they were able to enjoy the ample outside space in the garden and use the trampoline to play.
The block is very secure and has ample car parking space behind closed gates, which is very useful if you arrive in a car.
It is very reasonably priced for what you get and it is always nice to have attentive and caring owners to deal with.
We would highly recommend this place!
