My girlfriend and I stayed at the Baan Sukhumvit Inn for a week, between 27th July to 2nd August. It was our first trip to Bangkok, and we're glad we made the right choice.

We had a fantastic experience, and most of the things mentioned on by others on this forum were true.

Kevin and co were absolutely splendid in making sure we enjoyed our stay. We wouldn't hesitate recommending this place, and hope to be back again.

The Good:
# Quiet end of Soi 20: It has two access lanes, one of which is lined up with some nice restaurants, including a South Indian restaurant. Sukhumvit Road is busy day and night, and can get fairly dusty / smog-filled at times.
# 2 minutes to the Asoke BTS station: walking distance, and perfect location as it's also close to the Sukhumvit MRT interchange.
# Everything you need is really close by. There are two 7-Elevens along Sukhumvit road, you could literally run downstairs and back to your room without breaking a sweat.
# Cozy room(s): ours was a standard room (1540 Baht), double bed, with an attached bathroom. 12 rooms in total. First impressions upon arrival were great, and we were never disappointed.
# Free WiFi: in your room! This was blissful. We had our own laptop, and were able to lookup places of interest at any point of time. Great tool to have on the go.
# Fresh towels everyday: prompt room service, and replenishment of all necessities. Thick quality towels on top of that.
# Excellent bed: not the cheap kind, we found this to be great for uninterrupted sleep. Perfect after a long day touring the city.
# Complimentary water: in Bangkok, never forget to drink your water. It's humid! The hotel provides two free bottles of water (500ml) per day. The mini bar is very affordable, and is only about 20% more than the 7-Eleven.
# Extra pillows: Loved the pillows, we even got an extra pillow upon request at no charge.
# Aircon & water heater which just works the way it should
# DVD player: not the best selection of DVDs, but you can plenty for cheap out in Bangkok itself

The Bad (Tiny Bad Things):
# Not much of a view: don't expect to see the Bangkok skyline. You're at the end of the lane, and will only be able to see some skyscrapers. Nothing fantastic.
# Poor acoustics in the hallway: you can hear noises from the hallway (3 rooms per floor) - e.g. doors shutting. You can turn up the volume of your TV to ignore it all.
# Boring breakfast meals: after a week, the American breakfast meal grew stale on us. Perhaps it may not be the case for shorter stays. Plenty of alternatives near by.

Other Things to Note:
# Don't pay more than 400 Baht for the public taxi from Suvarnabhumi Airport to the hotel. Ask Kevin for instructions on how to get a taxi from the airport.
# For our return to the airport, Kevin's team gladly booked a taxi for us at 360 Baht.
# Don't have an itinerary? Ask Kevin for advice. He's got loads to share about the city. Friendly staff members can teach you lots about the language too.
# Getting to the hotel for the first time may be a little difficult via taxi. Our taxi driver couldn't locate the hotel. But just keep an eye out for Soi 20, and get off the moment the taxi turns in to the road. It's easier to just walk into the quiet lane towards the hotel.
