Had a pleasant stay at Blanc Guest House. Staff are friendly and efficient. Room was spotless and nice touches with complimentary water bottle and slippers. Location is quiet but quite a walk from the main tourist areas, although it is easy to navigate the public transport system - I found buses, from bus stops close by, were frequent, reliable and a better option than metro.
The downsides of the guest house for me was the noisy air conditioning unit in the room and the repetitive breakfast. This wouldn’t be a problem if staying for one or two nights but for a weeks’ stay, it is tedious and lacks balance and nutrition. Cheese slices, processed chicken slices and salmi, granola, muffins, biscuits, pastries, cakes, chocolate roll, brioche, and white and brown bread plus a sparse fruit bowl. Young kids seemed to love the sugar overload breakfast but not the adults.
Overall, I would recommend the guest house for a short stay but not a full week.
