Hi Pamela
Narai is worth a try - it's a big, rather impersonal hotel, but excellent location (just near Silom Village) and good value for money. Rooms are modern and fine. Pool area is on the roof and a bit small but the hotel is clean and safe and the staff were friendly and spoke decent English. I must confess I haven't stayed there for a few years but I have fond memories and it was perfect for me at the time.
It's about equi-distant to the Chong Nongsi and Sala Daeng BTS stations - they aren't right next door, but a healthy walk, especially during the day (not so great at night!).
These days I stay at the Pathumwan Princess as I find the location so fabulous, but it's more than double the price of the Narai ... rooms are actually of a pretty similar quality (but Narai rooms are smaller).
I've enjoyed reading your many posts over the years and I just know you aren't the sort of person to spend lots of time in a hotel room, so the Narai is worth considering!
Incidentally, I'm back in Bangkok in May (again, staying at Pathumwan Princess) and will be booking for the first time with Asiarooms. I checked the latest Qantas Holidays Brochure (I live in Melbourne) and PP has gone up to A$165 per night without breakfast ... it's A$125 including b/f on Asiarooms, which is a considerable saving.
Both Narai and Silom Village Inn are listed as 3 star hotels ... I haven't been to SVI but I do know it, as it's attached to the Silom Village shopping and cultural complex ... Asiarooms has Narai for A$63 including breakfast and SVI is A$39 without breakfast.
The link for Silom area hotels is
Silom Hotels in Bangkok - Bangkok Hotels - Silom Hotels Area Discount
I really do tend to shop around and these are the best rates I've found - BUT, I have never used this booking service before, so can't vouch for it yet - stay tuned for my post after the May trip!
Good luck, and I"m sure you'll love the area. I've got a couple of great restaurant recommendaitions too, if you want them!
Warmest wishes
Daniele
